Just talking here. One of our cats gave us such a scare. Heard a cat shriek from the other room and I came running. Sage and Eclair both had puffed tails, and Cookie was looking on. Because Cookie and Eclair don't always get along I thought they had fought and Sage was upset. Sage is kind of mothering.
Then I saw blood. LOTS of blood. Dripping down the radiator, along the windowsill, on the floor. I looked at Sage who had a bloody paw.
We figure she was climbing the screen, as she likes to do, and broke or pulled out a claw.
I picked her up. Blood all over me. Tried to look, but she kept pulling away. Wrote the vet.
Luckily the bleeding seems to have stopped, and she doesn't seem to be in too much pain. She is favor the foot a bit, but she is jumping up and down onto things, eating (at least a liquid snack as well!)
So... calming down now. The vet suggested disinfecting it with a bit of salt water.
