High horses? Sorry, this has got to be said.....every day a large number of these people watch kittens no older than six months either die or be PTS because a home can't be found. Sometimes the cats are even younger, and an old cat has massive difficulty finding a home. Peoples opinions on your allowing your kittens to breed was made abundantly clear last time you posted about it; maybe you should have taken that on board and refrained from mentioning them if you didn't want polite responses steering you away from the idea. There's a whole post on the dangers a female is exposed to if she isn't spayed; and some of those dangers increase with every season she comes in to. I apologise if this is abrupt, but the number of cats needing homes are rising rapidly and any kitten born purposely is taking a home away from another that already exists and needs somewhere. Yes, rescues do checks, but surely you can understand that is necessary to ensure a safe home? And I agree that some rescues charge too high an adoption fee, but if you look long enough you'll find one that is reasonable and understands that sounding out a person is more important that money.
With regards to Ken, good luck at the vets. He sounds an awesome old man and I'm sure a lot of folk on here were sad to read you weren't going to post again as we wouldn't find out how he went at the vets. (I didn't realise you meant Woody and not Ken when you said the vets might say it was his age. It might well be, but it doesn't mean they'll say the same. I think it's a natural worry though, that we all get when our cats get older. We're scared of the inevitable "there's nothing we can do to help" conversation.)
Again, apologies if this sounds like I'm judging you. It's more that I've become very involved in raising awareness in the last few years of overbreeding in companion animals and the number of cats and dogs being PTS purely because no homes can be found and there aren't any rescue spaces is horrifying. If you need actual figures to illustrate the matter I'm sure I can get them from one of the rescues.
