We've had a very big ginger (with a bit of white) cat in our back garden chasing and biting our wee fella. I've been to the vets twice now cause of that cat. 100quid it's cost me so far. I've seen it chasing my cat in the garden a couple of times now, if I catch it I am going to give it one almighty kick in the balls. On another note. We had another cat (black, white and maybe with a hint of ginger) coming into our flat every day for 2 weeks. Was coming right into the flat at night. Had to get a infra-red cat flap fitted to stop it coming in!!!
