8 year old neutered male. Basically has been a miserable sod his whole life. Hates being picked up. Spend lots of time outside but will sleep inside at night. Not massively affectionate. No health issues I am aware of. Last few weeks he has been seeking out attention and in particular loves if you rapidly pat him at base of tail. Its like crack cocaine to him. This is a new thing. All very odd. Any ideas?
