My future cats

I have been thinking about my future cats. I keep on making excuses for when I should get them. First I need a catdoor in my balcony door, but after checking out the cost I think I perhaps won't need that. My cat-owning friend agrees. Then I need to find a veterinary in the neighbourhood. And I need to buy a cat toilet, a cat transportation thingie and so on. And what if I need to leave my home for more than a day? Who will take care of them? Think I'm just being stupid. I want cats. I have had cats before. Why am I waiting?
