Are you looking to get a cat? if so, check out PetSmart. My wife and I adopted a kitten here and she's awesome.
There are always several cats (occasionally dogs) looking for a good home, some older cats (a few years old and some kittens.) There is an adoption fee, but the cats will come with their shots and are neutered/spayed.
We also use this store to get both wet and dry food and toys on occasion. There are many sizes and brands to choose from at good prices. The food is cheaper at PetSmart than Petco, unless the item is on sale.
I would recommend to get a PetSmart card to save a few bucks.
The store is always clean and staff very friendly and helpful.
