Dcat does not get one with one of the neighbouring cats, when ever they meet there's a lot of yowling hissing and spitting but today it seems to have a full blown fight. I heard a lot of yowling and found them inches a part with a load of grey fur between them(dcat is grey). Dcat wouldn't come in, wouldn't let me near and was hissing. I was wary about approaching as I know wound up cats can sometimes just attack so left him to calm down.Now hiding upstairs, won't come down, has eaten a few treats but seems to have a slight limp and is quiet for him. If no better in the morning I think I'll have to take him to vets
