I have 3 cats adopted in the last year. They have become accustomed to their indoor litter boxes but this was never the plan. Currently have 1 in the bathroom and 1 in the hallway outside the bathroom. I had a third for a while but there was no space left. Currently trying to figure out where to put them as it's awkward for guests. I live in a ground floor 2 bed flat. It is a long hallway and I have very little other rooms to put them in.
Any ideas please, or do I take the decision to make them go outside?
