Certain animals, because of domestication, cannot survive any longer in the wild. Those animals need homes, and the more that have homes, the fewer there are to roam the streets waiting to die or trapped in cages. Breeding is terrible, and I don't agree with it at all. I have pets, all are rescues, and I see absolutely nothing wrong with it from an animal rights perspective. They have love, food, and shelter that they wouldn't have if it weren't for me.
I have three dogs and three cats, two dogs are from breeders and one dog and all the cats are from rescues. I feel like these animals would be alive whether I owned them or not, so why not own them? As long as you're providing an excellent home for them and they re happy with you, then there are no animal rights being broken. While rescue is of course best, there is a difference between getting your pet from a breeder vs. a pet store. Pet stores obtain their dogs/cats from puppymills, which is pretty much a place very similiar to the egg industry except instead of eggs those dogs/cats are producing babies to sell cheaply to pet stores and internet businesses. A real show breeder is there to keep the different dog/cat breeds alive, without them there would be no pure bred dogs/cats. While that may not seem important to the lover of mixed breeds dogs (BTW I used to have one) it is important to lovers of certain breeds of animals as well as their history.
I have two cats,one is 19 and one is 16,both ladies.Although I am vegan,I buy them very good food with salmon and lean chicken in it.And my old lady,the 19 year old,I give her fresh salmon several times a week.It's amazing how much better her eyesight,fur,agility and energy are with it.I don't like doing it,but for her sake I do it.I know I'm improving and extending her life.The younger cat doesn't know what fish is so I don't give it to her really,kind of a waste when she isn't appreciative!
