I'm going to pay for my outdoor cats vet bills and still keep them outside
Why do you need to keep them outside?
They are my outdoor cats, they live inside home too often and I always feel that it is annoying.
Since they're an outdoor cat, it is good you are respecting their nature. Good on you for going to the vet regularly because you never know what kind of dangers your outdoor cat might run into.
Those indoor cats are just stupid, I don't want to think about indoor cats problems anymore.
All animals are wonderful whether they live inside or out, wouldn't you agree? It's not fair to discriminate between these cats, as they will show you love regardless of where they are from.
