We have a tabby cat who is nearly 11 years old, he has been very healthy apart from last year when he attacked by a fox or dog that left him with a huge abscess on his leg but was treated successfully.
But for the last 3 weeks his behaviour has changed, he rarely leaves the garden, choosing to sit in one area for hours at a time, he is jumpy and nervous and is far more vocal, he also seems to sit and stare at nothing for several minutes at a time.
He is eating a bit less, drinking normally though.
Is this normal aging? My teenage dd will be distraught when he dies and she is worried about him.
