I nearly went crazy , my cat came in and collapsed on the kitchen floor .When I tried to pick him up he yowled and dragged himself upstairs with his front paws. he got on my bed ,i dont know how , then bled all over the duvet. Everytime I tried to touch him ,he yowelledand spat and hissed like crazy . Ever tried to get a vet to come out early on a Sunday morning!! He calmed down, I calmed down, he stopped bleeding He went imobile - wouldn't move. I surrounded him with hot packs He stayed on my bed all day and all night . In the morning he purred!!. He couldn't move all week .One week later he's completely back to normal. Me --I cant believe it all happened , I think a fox attacked him . I dont let him out early on Sundays now
