I think it's nice to see people rescue dogs/cats either from outside in bad situation or from shelter/pound. We had one cat who came from a dog pound (yes, dog pound with dogs AND cats) the cat was totally terrified being there.
unfortunatly that cat was lost as my mom left the patio door open (cat was VERY curious - probably now dead or in another home - wish I knew, it bothers me...). Our current cat was from a "breather" but a good one. Was the local vet who bread cats and sold them, so they were healthy, and she also would keep up with them as they grow/need needles/proceedures etc. The mother cat would usually have a batch every 6 months from what I recall, then she stopped when the mother was older, I think she sold her or kept her around. All was done humanly and not just speed up to make more money.
It's so fun to have a kitten though, oh man, they're so funny and cute.
I've heard and seen videos of people rescuing a baby squirrel and the cat or dog takes care of it (usually with existing kids) and it actually grows up to be domestic. Now THAT would be freaken awesome. Think, a kitten, but 10x the energy. lol.
If ever I get another pet I'd probably go check the shelter first, if not a quality breeder like the vet we got our current cat from. The beauty of getting them from a breeder is you get to watch them grow. I'm sure I'd end up getting attached to one at a shelter. The danger is I'd want to bring them all home LOL. I see nothing wrong with people who have like 10 cats though, as long as they are well taken care of and the house/litter etc is cleaned.
And OMG @ the kitten found with it's dead mother, that's just horrible that someone would do that. good rescue.
