Just come back off holiday. The house smells awful. Does it always smell like this? I've one elderly cat who has had a few accidents in past but cat sitter said no accidents this week - she put an extra tray in, just in case but oh my goodness. It stinks. Not if we. Just of "cat" like the battery smells. Maybe it always smells and I've been nose blind?? 😱😱. But I've not noticed like this before after holiday. I've googled but it's all advice about wee smells
Any ideas or honesty about it? Maybe it does smell always??
