I only need one reason.
If I am a breeder who has a few cats who have at most a few litters a year, I get attached to the cats. They live with me. They’re all my own cats, until they go to a new home. I see them go from being tiny specks of life who can’t even see, to lively, lovely animals with a personality of their own.
If I am a pet store owner, I don’t raise the cats. They don’t live with me. They live in cages in the store. I haven’t seen them go from being newborns to kittens. I’ve invested money in them, but nothing else.
Who is going to be more attached to their cats? A breeder or a pet store owner? Who’s more motivated to treat the cats like they matter?
Stores are all about appearances. As an anti-show groomer, I say a healthy appearance can be faked. Diarrhea can be cleaned up. Vomit can be cleaned up. Eyes can be cleaned. A sick cat can be made to look healthy. Happens all the time.
*Probably don’t need to say this, but when I say “breeder” I’m not talking about kitten-mill breeders.
