The Diagnosis of Malignant Melanoma In My Cat 

A Tribute to My Beloved, Beautiful Cat Marcello

My 15+ yr previous rescue cat Marcello was all the time the image of well being. He handed his annual routine checkups with flying colours yearly and solely wanted two dentals within the 12 years he lived with us. No sniffles, no sneezing, no coughing, no viruses, no infections. He couldn’t have been a neater cat to look after. Till he began peeing outdoors the litter field. That’s when issues began to vary. That was a yr and a half in the past. 

Marcello lived with three different rescue cats upstairs on our second flooring. He would have been very pleased as an only-cat, however sadly that was not his future as I used to be in cat rescue, and was actively trapping deserted cats in our group, bringing them house to foster, medically deal with and socialize them, earlier than placing them up for adoption with my cat rescue group. One after the other, there was all the time a brand new rescue cat that Marcello needed to put up with. He hated the competitors for consideration and would even punish every cat for stealing affection away from him. He was a one-woman cat and that needed to be understood by any new resident cat who got here to share his residence–these have been the bottom guidelines and Marcello strictly enforced them.

A Tribute to My Beloved, Beautiful Cat Marcello

Marcello himself had been deserted. Somebody who owned him in his early years had left him behind and moved away, leaving him to fend for himself outside. Marcello survived, however he had been in his share of cat fights and had the scars and torn ears to show it. However his actual wounds have been all on the within—his belief in individuals had been deeply injured and his confidence in individuals shaken to the core. In the course of the first two months of Marcello’s therapeutic with us, he feared being deserted once more. Each time I came around him in his room, he utterly let his guard down and would wrap, twist and curl his physique throughout me, then head-butt me time and again, all with an enormous orange tail flared out like a bottle brush. However once I would rise up to go away, Marcello would assault me like a police canine—and chew my ankles with a vengeance and depart me a bloody mess. That worry of abandonment slowly dissipated over time as he got here to belief and understand that he was protected with us. Briefly order, Marcello turned one of the affectionate, loving cats I’ve ever come to know. He was a cuddle bug who liked nothing greater than being stroked, rubbed, petted, caressed and beloved each minute I might give him. 

Quick ahead to immediately. For over a yr, Marcello had been peeing on all of our rugs upstairs, in addition to peeing outdoors the litter field, and even pooping on the ground underneath our desk. He had been to our vet 3 times in a yr to check him for a potential urinary tract an infection (UTI), or bacterial an infection or urinary crystals—however each urinary check got here again unfavourable. Since we dominated out an infection, we assumed then that it was behavioral. So, I went to work making an attempt to scale back his stress and nervousness, and create a safer surroundings for him. I modified the litter field places, eliminated some litter field covers, added extra litter bins, added new toys for enrichment, purchased the plug-in pheromone Feliway diffuser and plugged one in each room, and rubbed drops of Rescue Treatment into Marcello’s ears, however none of those modifications labored. Marcello already had loads of hiding locations, protected packing containers in closets, his personal cat beds up on closet cabinets, and had 7 ft tall cat timber to climb atop. I lastly reluctantly resorted to making an attempt a few anti-anxiety drugs, however after two months, even these didn’t make a distinction. To Marcello’s chagrin, I did the one factor I might consider as a final resort—I transitioned him to stay in our cottage with three different rescue cats. However he was depressing together with his new kitty roommates. This was simply an excessive amount of for Marcello, he shortly grew depressed, anxious, and burdened, and was nonetheless peeing. Now he was even peeing on his personal cat beds. So as soon as once more, I loaded him up and off we went for an additional physician checkup, this time I wanted to resolve what should be blamed for this continual drawback. One thing bodily was inflicting this I felt, I sensed it was not behavioral. 

The Diagnosis of Malignant Melanoma is My Cat

On February 10, 2019, I took Marcello to our veterinarian once more Dr. Laura Becker, to run diagnostic checks as soon as once more for his inappropriate urination. More and more Marcello had been licking his stomach and “mowing” his hair, he had additionally began obsessively licking his prepuce space, inflicting the dilation of his prepuce that had now turn out to be giant and uncooked from his neurotic licking. Throughout his examination, Dr. Becker observed with nice concern how his prepuce had considerably thickened in circumference, and he had a slight however distinguishable blue/black discoloration on a part of the prepuce pores and skin. She shortly commented that the discoloration was a attainable tumor or most cancers. I used to be surprised. This remark was so out in left area for me. This was not the result or analysis I anticipated in any respect, and most cancers couldn’t have been farther from my thoughts. I by no means had a cat with most cancers. She sedated Marcello and took a number of tissue biopsies and needle aspirates from contained in the prepuce and despatched them to a lab in Davis for analysis. Whereas on the vet’s workplace, Marcello was given a steroid injection to scale back the dimensions of the tumor and we went house with an anti-inflammatory NSAID medicine referred to as Meloxicam to regulate the irritation and progress, and to scale back ache. 

The biopsy outcomes got here again a number of days later and revealed the worst attainable end result for Marcello—Malignant Amelanotic Melanoma. This was adopted by Neuro-Endocrine Carcinoma or poorly differentiated carcinoma inside his prepuce, which might ultimately develop to trigger him to be unable to urinate. Each are aggressive cancers that develop and unfold quickly to lymph nodes, lungs, bones and the liver. Malignant Melanoma could be very uncommon in cats—melanomas usually, comprise lower than three % of pores and skin tumorswith roughly 42-68 % of these being malignant. And malignant melanomas account for lower than 1 % of oral tumors in cats, in accordance with Tufts College. However sadly, of their malignant type, melanomas are typically very damaging regionally, and re-grow after surgical removing after which metastasize or unfold to different places within the physique. And in contrast to in people, melanomas in cats are unlikely UV-radiation associated. Although it’s thought that trauma is suspected as a predisposing issue since melanocyte cells divide when they’re injured. Most cats and canine get melanomas on their head, of their eyes, or inside their mouth, or on their decrease legs. However Marcello’s melanoma was in an virtually unheard-of location, the oncologist stated he has by no means heard of a case like his. I knew I used to be in hassle. 


On the pathologist’s workplace, a Fontana Masson stain was carried out to additional help and confirm the analysis of malignant melanoma for Marcello. The outcomes of his blood and urine check got here again completely regular and wholesome. Every part I examine malignant melanoma in cats stated the tumors are very aggressive cancers. The prognosis is often not good, and the chances of long-term survival are poor. The most effective remedy  for this most cancers is full surgical removing of the unique tumor, however the location of the tumor on Marcello’s prepuce made that inconceivable because the location is just too delicate and can be too painful when urinating. Radiation remedy was an choice that I mentioned with my vet, however once more given the delicate location, and taking Marcello to an oncologist so many occasions for remedy beneath anesthesia – I couldn’t’ put him via that. I accepted that my Marcello was dying. 

Hoping for the perfect, I began Marcello on Gabapentin, a pain-killer, daily, together with Meloxicam, a non-steroidal anti-inflammatory each different day. I utilized an antibiotic ointment to his prepuce morning and night time, which I switched to Lidocaine later to numb any ache or discomfort he was feeling in that delicate space. As well as, I gave Marcello fluids each different day to maintain his urine clear and dilute to keep away from ache whereas urinating. The worry I had, and it turned out to be true, was that his most cancers had already unfold. 

Sadly, malignant melanomas are typically actually damaging regionally, and even after surgical procedure to take away the tumors (if we might), they metastasize and unfold shortly everywhere in the physique. I had began researching and studying each publication on the subject, and located the prognosis was extraordinarily poor for him. Lengthy-term survival charges are extremely unlikely. And as soon as the most cancers has metastasized, the cat will probably stay solely 1-2 extra months. I used to be surprised. So our assault was to decelerate the most cancers’s progress with first anti-inflammatory Meloxicam, however when that didn’t work, our vet really helpful a day by day dose of the steroid Prednisolone. What we didn’t know, is that his most cancers had already shortly unfold to eat Marcello’s lungs. One month after his analysis in February, I took Marcello again to the vet to see if I might discover out if his most cancers had metastasized and by how a lot. I needed to understand how a lot time I had left with him, if any. 4 weeks later, on March 15th, I took him in for X-rays and we discovered his lungs have been a cob-web of most cancers. I suspected one thing in his lungs as a result of Marcello had began coughing—uncontrollably, adopted by lengthy durations of speedy, shallow respiration the place he was stiff and nonetheless. These episodes actually bothered him, he appeared ashamed at his lack of management. His new cough certainly involved him as a result of he would slink up onto the mattress together with his head hanging low—like he was saying “I’m sorry mama.” I felt a lot guilt for not with the ability to assist him or heal him, and even purchase him extra time—with much less struggling. I simply didn’t need him to endure, or die in agony, and I used to be tormented about what to do for him. He nonetheless had an excellent urge for food, beloved being petted, and slept properly, however he hated the lidocaine I placed on his prepuce. Then every week later he began choking on his tablets. That’s once I knew I used to be actually in hassle if I couldn’t give him his drugs. So I mashed his drugs into Gerber’s child meals and syringed them into his mouth, one by one, however that solely lasted a number of days. His lungs have been having problem now with swallowing something that wasn’t delicate. And the most cancers underneath his pores and skin round his prepuce was rising—spreading like wildfire, it was like a monster inside his physique now. And over time, he turn into extra delicate to those exhausting plenty, whereas they didn’t hassle him earlier than. 


By Friday, every week after the X-rays have been taken, I might see there was extra ache and discomfort, and fewer pleasure for him. The scales have been tipping—quick. Sunday was quick approaching, the day my vet’s workplace was closed, which is all the time a scary day for me. I used to be frightened that Marcello’s lungs may shortly turn out to be consumed in fluid, suffocating him, and I needed to keep away from taking him to the emergency hospital—a brand new place for him. His price of respiration had elevated to double the traditional price, and that was around the clock, so I felt the time had come to let him go. I used to be struggling a lot with this choice, as a result of I’ve all the time had cats die of previous age, or stay so lengthy their organs began to fail—I had by no means needed to let an in any other case wholesome cat go. It felt so unfair, so unjust. However I reminded myself he had lived 15-20 lengthy years, and 12 of these years have been very snug and glad. I assumed, what would Marcello need? What would I would like if I have been him? Or if he have been me? Cats reside within the current, within the second—to them, there isn’t a “future” as we all know it. They don’t see a future, or lengthy for one, or stay for one. Marcello’s life was not going to get higher, it was going to worsen—and quick. So, with the assistance of my fantastic, loving cat associates who rallied for a session, and reaching out to a cat communicator, together with my vet—I made a decision that it was time. I made a decision to let him go the subsequent day, a day earlier than Sunday. And my trusted, compassionate, expert veterinarian Dr. Becker was fortunately engaged on Saturday—she saved the final hour for me and Marcello. All for us.

I spent all the day with Marcello on Saturday, feeding him as a lot Gerber’s child meals as he would eat, studying my ebook on the mattress with him as he slept, giving him infinite pets and hugs and kisses because the hours previous, and let him understand how very a lot I liked him. I thanked him for locating us, and for entrusting us together with his lovely soul that so touched our lives. I thanked him for all the love, head butts, squinted eyes, physique presses, nightly purrs, bottle brush tail that flared when he was glad, and the love that he shared with me daily for 12 lovely years.

I introduced Marcello into our vet the final hour they have been open. It was quiet within the workplace. I carried him in an enormous, tender, fluffy purple blanket that he had come to know and was conversant in. We sat on the couch in a quiet room with low-light designated for doing euthanasia procedures. Marcello curled up burying his head in my arm pit urgent onerous towards me, getting as shut as he probably might. We sat there for a very long time, simply being. He by no means even felt the sedation stepping into ever so slowly, he had had fluids each different day so he was used to the poke in the identical place and feeling of the fluids getting into. To him it was simply one other day. Slowly, ever so slowly he fell asleep with the sedative, and he by no means knew what occurred after that second. He fell asleep and died in my arms. That’s how I needed it for him, him figuring out I used to be loving him until the very finish. 

We’ll love you perpetually Marcello, you’ll by no means be forgotten, you’re in our hearts for so long as we reside. We’ll see you when it’s our time to go, once we will be a part of you on the opposite aspect, over the rainbow bridge. Bye my loving buddy.
