Until recently we had a lovely cat that used to wander into our garden (sometimes sleep) that supposedly didn't belong to anyone.
The market cat (used to eat there and was well loved) also saw to our mouse population as he'd pop through the window.
Sadly the fat market cat is no more, he was fairly old and lived the life.
I've always wanted a cat but was never allowed one as a kid and I moved around a lot until now. Discussing my sad catless life with my housemates they all jumped at the idea of me adopting one as a) the mice have moved in b) they have all owned cats in the past.
Now, the church who owns our house are very relaxed/have never done an inspection/market cat also hung around during the services would turn a blind eye. My biggest issue would be adopting a cat that wouldn't be house trained or a cat that would claw the wood in the house.
We have a few acre garden so would be perfect for a cat who was sociable/loved being outdoors during the day.
How much can you request of a cat's characteristics from a rescue?
