Shame that mate. I have to put mine in a spare hutch when I clean them out cause my sisters cats quite interested in them. Surprised when you said they killed your jill, i don't think my cat would dare, she's tried it once to many times through the mesh and got a bad nip on her foot. She just looks now from about 10ft away, still i don't risk it. About keeping the cats out of the garden you can get those cat and dog reppellers fairly cheap might be good buy. Sorry for the essay ATB Dan
