I am the very proud owner of a nearly 5 month old cat who uses the toilet! Few times a day, I do a quick flush and a wipe round the seat with nice smelling dettol spray on loo paper, flush that and walk away.
Took about a month and was not convinced about training such a young kitten but he's taken to it like a duck to water. Sorry for gloating but I am chuffed to bits with him 
Is anyone else training at the moment?
