We have two cats - brother and sister, both 15 years old. The male has started wailing in the last six months. Vet has checked and said no physical health issues and that it is likely a sign of cognitive decline. Nothing we can do.
He has been showing signs of confusion - staring blankly, not responding. But then a moment later is back to his old self again.
But this morning he attacked his sister very aggressively - I heard the most awful noises from upstairs and ran down to find him on top of her with his jaws round her neck and fur everywhere. I shouted and clapped but he didn’t release her and I had to physically pull him off her.
He was very odd afterwards - sitting staring etc. But now he is curled up on my knee and back to normal.
His sister is not injured but was shaken for a few hours after (hiding under bed trembling).
What do we do? Grateful for any advice. We love them both so much.
