Wow, your post was long. You might have gotten five or six threads out of this one post. (chuckle) I too believe that indoor cats don't need to be vaccinated for everything that comes down the pike and my three year old calico has only been to the vet once in her life... to get spayed. She went in perfectly healthy and came out with ear mites that I then had to treat. She's never had any other condition the whole time I've had her in my home. I've had cats my entire life and the longest lived one was around 19 when he died but he had seizures and other complications from eating lead-based paint as a kitten. (He had Pica and would eat non-food items all the time.) Another lived to be about 18. I'm hoping that my girl has a very long life. I try to feed her well, though she can be a bit of a fussy eater, preferring 9-lives dry food and people-style tuna or ham over canned cat food. She's an indoor cat and can't go outside without my husband and I because we live in an apartment complex with a bunch of idiot drivers who never watch where they're going. She's pretty much afraid of the outside anyway, though she does ride well in the car. Good luck with your two old gals and I hope the sick one gets better and can stay with you a little longer. I think 26 is a remarkable age for one cat, let alone two, so you are definitely doing a lot right.
