My old boy cat is tearing his fur out in stress because foxes have been coming in through the cat flap. For a long while me & the vet couldn't fathom the hair loss? My cat who has always been very timid, made a large section of his back bald. (turned out he was hair-pulling due to stress). I finally got suspicious after ruling out medical reasons for hairloss & set up a web cam to see if other cats were entering the house. Imagine my horror to see it's a bloody fox! There is no food left out but it had been on my kitchen worktops! Foxes just don't give a toss these days do they? I'm now probably going to have to brick up the cat flap & make my old boy an indoor-only cat. Anyone else had this problem?
