I was woken at 6 AM by the sound of a cat fight, a real humdinger. I jumped up and found all the cats in a high state of excitement, yelling insults at a large tabby who was peering in the French doors. They were also having a go at each other, the hormones had kicked in. I clapped my hands on the door and the tabby ran away, then tried to calm them down. But Wellington rushed upstairs to look through the top windows, decided that was no good, leapt from the window sill to the stair banister, missed his footing and fell about 12 feet to the bottom of the stairs. I rushed down again, to see him sitting on the rug, holding a paw in the air and looking shocked. Of course I thought he had broken a leg, and approached him carefully. But he seemed to be alright when I touched him and eventually I picked him up and sat on the sofa with him while I examined him all over. Other than being dazed, I think he is fine, but he just wanted to cuddle for half an hour. He has eaten and pooped since then, and is now sitting on my bedroom windowsill watching the ponies and the birds. He is walking OK. I shall watch him carefully today, but I don't think a vet visit is necessary unless he shows some other symptoms. I eventually found loads of clumps of black cat hair by the kitchen window, but I can't find any signs of damage on Dushka or Ellie, so I don't know which of them suffered in the fight. All the cats are a bit subdued this morning - obviously they had a hard night.
