Most days, my cat and I go for a walk (and a bit of hide and seek) in the graveyard at the back of my house. We reach a certain point that he doesn't want to go past - he hisses, growls and yowls at me. It's by the same gravestone each time.
There's nothing out of the ordinary that I can see. Not a particular spot where dogs mark their territory or any other cats around. True sceptic here, so what do you think? He's fine if we turn round or go past it.
