These two little jerks had to be separated for almost 6 months due to serious fighting between them. Pretty sure it was re-directed aggression from seeing an outdoor cat. It was almost to a point that we were going to re-home one of them... Anyway, we stuck it out & re-introduced them & now they're back to living together semi-peacefully. Cats are weird animals...
Your cat is very good at blending in with the background. Cubby hole top right corner but I might be missing another cat which I think is hiding top right in the white cabinet.
