I have a 4yr old brindle tortoiseshell female, no specific breed, was spayed aged 6months when we got her. She is (99%) of the time, extremely lovable and affectionate, comes when we whistle and obviously loves us. However, over the past 6 months we've noticed a disturbing change in her behaviour. At night, when we go to bed, she has starting attacking me by leaping from the floor onto my head on the pillow. I'm not sure when the first time was, but the worst was on Feb 16th when she scratched the soft part of my eyelid, just under the brow and when I looked in the mirror my face was covered in blood and I couldn't open my eye the next day as it was too swollen. Then for a while, nothing. And now, she has tried to do the same 2 out of the last 3 nights. On the one night that she didn't I woke up to find her cuddled up to me under the quilt - such a contrast. I don't know why she is doing this - we haven't moved house, changed jobs or got any other pets. I know she has started going next door into our elderly neighbour's house and that they give her ham and treats but we don't give her anything like that (a few felix chicken lickins when we remember but that's it). My husband says if she hurts me again like she did in February he will have her put down as I could have lost the sight in that eye had her claw been off to one side. We both love her to bits but are at a loss of what to do. Does anyone have any suggestions?
