She is 8 months old and loves going out. In particular there is 1 big fat tom cat that follows here every where.
When I come home from work he is in my house. We have caught him in our house 5 times now. Don't think it's upsetting her but he eats her food and I'm worried he'll start spraying around my furniture.
Short of locking the cat flap (which means she'll have to stay in all day) is there anything we can do?
