We have a cat who used to use a litter tray with no problems. We had him neutered and tho he still uses it sometimes, he now wees/poos anywhere. I clean up the mess each time, soak it with the odour solution stuff AND spray it with repellent.
I have tried changing the type of litter, emptying it each time he goes, OR leaving it a few days to build up his smell. We have to shut him out at night then he runs inside first thing and finds somewhere to wee.
Its driving me bonkers. And my house stinks.
Any suggestions on de-odourisers, or litter or behaviour management?? PLEASE?
