Not according to a post earlier in the thread. I tried to quote it but it won't come up in my post. It pops up in the edit window, but then disappears when I post.
It was #7 with @Laura Cynthia Chambers quote from Memory Beta. I'm thinking it must not have liked that I was quoting a post that was just a quote.
We see Spot in Nemesis. B-4's petting her before he goes to grab the fleet movement information out of the Ent-E's computer.
Some cats live until their late teens/early twenties with a high quality of life, and that's now. I would think by the 24th Century, feline life spans are probably increased just as humans are.
Not a given, though. It's only some cats. Even if future medicine increased the average, it wouldn't mean every cat lived that long.
Spot lived on the Enterprises, D and E, after all. More timely access to better medical care, surrounded by scientists, and owned mostly by Data, an android that can remember anything he reads. If any cat is likely to live very long and prosper, it's Spot.
Also subjected to the stress of frequent space battles, the health hazards from weird cosmic phenomena, the occasional mutation into a reptile, etc. And even cats who get the best medical care aren't guaranteed a long life. It just improves their chances. When I got my cats Tasha and Shadow as kittens, I was confident that, with modern medical care, they'd probably live into their 20s, but they only made it to 17 and 19, respectively. And both had brushes with death when they were only a few years old, thyroid disease for Tasha and a right-of-way disagreement with a moving car in Shadow's case. There are no guarantees.
Also true. Still, the Enterprise is one of the cutting edges of science, after all. If Spot had been on a cargo freighter or a passenger liner and met with similar stresses, the chances would be less favorable. Nothing is guaranteed, indeed. If they're making it that far in the 20th-21st century on Earth living normal (relatively speaking) cat lives, then Spot? Who knows?
