I hope I am at the correct forum. I have 4 babies male neutered 4 years old male neutered 2 years old female 2 years not yet spayed and rescue kitten male now+- 7 months old making an appointment at the vet to get neutered. All my cats are FULLY INDOOR and never go outside. They are all on an excellent spread of dry and wet cat food all are very healthy. Have enough litter boxes with crystal sand some of them prefer the fine crystals others the bigger crystals so I have boxes with each. Last night one of them pee'd on the floor directly below where my pillow is. The pee was all over the floor, night frill computer my A4 book but I mean a huge puddle of pee this has never happened before. Anyone have some advise for me? And to maybe which cat would have done it? Thanks
