Yesterday, I was leaned back in my office chair, taking a mandated break from the sketchbook painting I was working on, my feet up on my desk. At this angle, the pear-like shape of my body makes a perfect day bed for Newcastle, who was purring and looking at me through hooded eyes, under the spell of the double-ear scratches he was getting. Once he was sated, he rested his head on my chest and drifted off to sleep, leaving me in this position for the foreseeable future, and I did something a little difficult to explain. I cried. I cried heavy sobs as I watched him curled up in a large, fluffy ball on my belly. It wasn’t particularly dignified, but I love this cat, and I don’t know what I’m going to do when he’s gone.

Nineteen years ago, I took a trip to Bloomington, Indiana, to meet my close friend, Kate. During the trip, we realized we were soul mates, and shortly after I returned home, arrangements were made for me to move from New York adjacent to her house on Stoneycrest Road. This was in June, and I would be moving in with her in August.

During this margin, she began to have dreams about a kitten who was about to die. She fancied herself a witch, so she took it as a prophecy and went to the animal shelter. She found the kitten from her dreams, and they were going to put him to sleep. He was a runt with pneumonia and a bad case of the worms. Also, he was ugly, with his greasy brown fur, looking like the transition from mogwi to gremlin. Despite the offers of a better cat, Kate adopted him and spent the next six weeks nursing him to health. She told me over the phone that she knew that this wasn’t her kitten. She didn’t know whose, but it wasn’t hers. This gross little thing was kept in the bathroom until he got better and her other two cats got used to him.

By the time he emerged, he was still a little greaseball, but he was a kitten who wouldn’t sit still for anything until he got tired and fell down to sleep. He’s also rock stupid. She named him Newcastle, after her favorite beer of the moment, because he fit in a pint glass and he had a foamy white chest.

Shortly after I moved in, he started following me around, occasionally taking naps with me when he slowed down long enough. Kate, who didn’t want to support another cat and was planning on adopting him out when he got well, knew she couldn’t break us up.

The runt grew.

And he grew some more.

My theory was that he ate some radioactive kibble. In actuality, he was either a Maine Coon or Norwegian Forest Cat mix. At only sixteen pounds at his largest, though, he was still a runt.

He never outgrew his kitten face, leading to Nicole calling him Baby Cat. (She had nicknames for all the cats when she lived with Kate and me.) Also, the brown darkened into a grayish black, with a spot of brown on his belly with the white chest, so that when we violated the two-pet limit in our high-rise apartment building, we pretended he and Magik were the same.

Like all of our cats while I was married, Newcastle is very social. He loves guests, and he especially enjoys parties, where he can beg for snacks, and he’s not even subtle. He loves people food, except for anything with tomatoes in it. When he was younger, I’d run to the bedroom and jump into bed, and he was right behind me, and we’d lie there together, cuddling. When Kate and I were taking a save-the-marriage quiz, guessing details about our spouses, her answer to “What’s your husband’s favorite animal?” was Newcastle. “You guys have a weird relationship,” she said. In our post-nuptial agreement that was the foundation of our divorce, we split up custody of the cats. She got the other two, and I got Newcastle. I almost lost him, though, because I separated broke and unable to afford his vet bills, which she generously covered for me the first three months following the split.

In 2012, we took him in for an ultrasound, and the vet made an interesting discovery. The reason he was often short of breath was not because of scarring from the pneumonia, as we’d thought, but because almost half of his liver was in his lungs. He recommended “cracking him open” and fixing it, but thankfully our second opinion said that wouldn’t be necessary. He was eight years old by that point, and he was doing fine.

Three years later, the vet noticed a heart murmur, and after another ultrasound, he was diagnosed with congestive heart failure. It had grown too big and was folding in on itself, necessitating semiannual cardiology visits and three medications every day to keep it from getting worse. two years ago, they added a fourth. Every two weeks, I cut up the pills and fit them into capsules so I can enjoy my least favorite time of the day, shoving it down his throat. Unlike most cats, he takes it like a champ, though he does look betrayed afterward. Last year, his back legs got really wobbly, and they told us he had arthritis (requiring a monthly shot), and earlier this year, hyperthyroidism (requiring an expensive ear cream). I don’t want to go broke taking care of him, and I considered not treating the hyperthyroidism, but all the pet docs say he’s pretty spry for an old guy (guitar riff). He could have three active, healthy years left if he’s properly medicated.

Sure he’s wobbly, sure he’s eight pounds lighter than he was in his youth, sure he can’t jump on my lap anymore, and sure, all he does is sleep, but he’s nineteen years old, and he’s been the most consistent relationship I’ve ever had. Since he is coming up on the end, I let him have some people food (he loves Fritos), and if he shows up, meowing at my desk, whether I’m writing, drawing, or working, I will scoop him up and give him all the attention he deserves. He’s earned it.

There were tears yesterday, but they were happy tears. He may be a big, dumb cat, but he’s my best friend. We’ve grown old together, and I love him so much.
