It seems pretty clear that your landlord doesn’t like cats, and is not pleased to have them in his rental. (It’s hard to imagine that some people don’t love your little fluffy as much as you do, but there it is.) It is his place, you lied, and I think you should be happy he is not throwing you out. ps. I expect that you know that some cats (not yours) can leave a smell that is almost impossible to get out of a house?
