It's cat country on my side of the park...more cats than foxes. It's three cats in 20 years though. I found two that had been run over at different times, and one that I think had just died from old age. Cats will sometimes go and find somewhere secluded to die. On all occasions I took the bodies to the nearest vet and in two cases the cats were chipped. The owners, although upset, were grateful they had the opportunity to bury/ cremate their pets, instead of them ending up in a council incinerator somewhere. I had one of my own cats die form a heart attack suddenly in the middle of the night once as well. By the time I got to the emrgency vet, she had died. That vet would normally have charged ?125 for the emergency out of hours service, but she didn't charge anything either. Most vets, in that situation, are pretty decent.
