Looks like there is something interesting behind that door! LOL
Maybe he smells something or hears something in there?
It also might have something to do with him seeing himself in glass on the cabinet beside the door. Not really sure, but those are my gueses! lol
Have fun figuring it out!!
Must be something back in there. It's great to see him doing so well (how are the runs? over with?)
Hehe, maybe he's just one adventurous little kitty! His reflection could be tempting him

Leo does this a bit-but he scratches (nails in) at the wall in certain corners-strange?
He is so cute... and he's keeping you on your toes for sure... I think he can smell or hear something that we humans cannot..
Maybe he's just adventurous and thinks if he can find a spot big enough, he can wiggle his way in between the cabinet and the wall, haha. Is that the only corner he's fascinated with??
I was going to say the same thing.....Is that the only corner he loves?
Thanks everyone, this is his his favourite corner lol. He does do it in other corners too, but mostly here! Behind the door is our hallway which leads upstairs and to the front door. He has a thing for running upstairs now and exploring (shhhh don't tell Martin! Martin doesn't want him upstairs, so we wait 'til he's at work!) He does sometimes look at his reflection in the cabinet, but mostly just sniffs on the corner lol! His poos all seem good at the mo thanks, he's on dry Orijen kibble for the time being until after he's castrated.
