Since you bring up spoiled, I've always laughed it off when people said my cats were spoiled. It surprises me to hear that but I just smile and think people are funny. I figure "cats are cats" and it's up to me to decide if I want to have cats or not, but if I do then I have to accept how they are.
Yes I have a cat tree in my living room, I scoop kitty litter, I buy raw food, I have to make sure they get bathed whether I do it myself or take them to a groomer, etc. But scooping litter is a lot easier than changing poopy diapers, yet nobody think the baby is spoiled. So what gives, are we really spoiling them?
