My landlord said no so I won't be getting a cat in the very near future.

He's apparently had very bad luck with tenants and pets in the past, and he said the lease was non-negotiable.

I'm really disappointed, but it's within his right as a landlord.

(But there's been a recent possibility of my moving in the near future, so at least I'll know that I'm ready when I'm in a place that's more animal friendly.)
