What are your personal thoughts on animal mills that supply pet stores with animals (whether they be puppies, rodents or birds, it doesn't really matter)? I feel like the consensus in general is that they're bad if the animals happen to be puppies, but totally alright if they happen to be rodents and other small pets which.. I've never really understood? Personally, I think animal mills are okay. Not great, not particularly ethical, but neither is mainstream meat production and most people still support that with their dollar for no other reason than they want to (which is a-okay in my book).
I plan to get a parti Yorkshire terrier and, while probably not a puppy mill, the breeder I've chosen is somewhat sketchy. I feel as though less "reputable" operations fill a necessary niche; some people want a rabbit or a kitten, and they don't want to be questioned, interrogated or otherwise have to jump through any hoops in order to get one. They possibly want a teacup variety, a non-standard color and so on as well which a hobby/show/reputable breeder likely will not have.
Convenience prevails and imo if someone has the money to deal with potential health problems (I mean, even certain breeds from supposedly good breeders have terrible health, like bulldogs), I think that's okay.
