Cat revenge. Tricky, sticky problem. Help.

[ClaudiaNaughton]

A couple of years ago we had a large black cat entering house at night thro cat flap and eating Claudiecat's food. Moved food upstairs and it came up too. We then installed all-singing all-dancing Sureflap cat flap which works only with our cat's chip. The black cat now visits at night and sprays its pungent urine outside over the threshold step and flap. Don't know where it lives.

Might the lion dung thing work? (You can get it as a garden cat repellant but I don't know if it works. Also it might petrify Claudiecat more )

It lives with you Claudia hadn't you realised?

If it's spraying like that it's probably an un-neutered feral Tom, you've locked it out of it's food supply.....

We've got one too, Grey and White, all singing all dancing cat flap not working as it looks like one of my cats has her chip too far down her back :-( I have found 'our' stray gazing at me in my bedroom in the dead of night ....

Can you put some food out at night for it? Aldi pouches are cheap enough.

The only room ASBO cats never ever sprayed is the utility room, because he eats and sleeps in there I suspect he wees in the sink though.

They do like to piss in the sink Fluffy.

Position their pee-parts over the plug-hole. Why though, when you've supplied fragrant and scratchy litter for them?

I agree with feeding the poor boy outside. Likely he's a stray.

poor boy is a vast fluffy alpha male. Not sure how he actually ever made it through the cat flap.
