Should pet bans be banned?

I guess the $300.00 non refundable covers the minor damage that can occur and carpet cleaning, things like that. 

Too bad Suzy scratched the carpet. Good thing you can put her in the kitchen now. I am sure she is fine in there.
You would have had some wear and tear on the carpet anyhow.

Most pets do not damage things. It is a rare occurrence. At least I hope it is. Did you end up getting renters insurance? I have never bothered.
