Hi I have one indoor cat. She is 9 years old. Gwen is her name. I have had a feral cat for 8 years living outside until this winter when it was so cold he decided to come in. His name is bell. I took him to the vet of course and all is well. The thing is they dont get along well. I mean I can leave them alone. They just go there own way in the house. I did use two litter boxes for months now. But I am seeing how they only use 1 litter box now. I was wondering if I can take the other one away. I clean out there litter every day.
