That sucks.

Apart from not being completely open about owning Piper and K'cee , can you offer to pay higher pet rent for three months and revert to normal rent if the owner is happy with the apartment inspection? Or let the owner inspect the place every couple of months so he/she is a little more secure that the apartment is being looked after?

I'd rather a pet owner than a heavy smoker inside, drug dealer, party animals etc in my home, but some people are prejudiced against pets I guess
