The only place I buy my supplies for Kitty nowadays because I can get 50 of her "blue" cans (she only eats blue) for the price that it is at Walmart. They also have a grooming station, and bunnies for sale, which always provides entertainment.
Kitty is very particular with no teeth and sensitive skin. She requires only the best wet food, and non-sented litter. I may or may not spoil her. But since that's not going to change, I might as well be able to do it on the cheap.
