Did you ask for more bond or increase the rent? We're in the same predicament. Although we are encouraged by all to allow for pets. I suppose if they've had the cat for a while and their previous rental history is fine then nothing to worry about hey? We've kept animals for over 15 years in the same rental, no issue with urine stains or urine on the carpet. We have 2 cats and they sharpen their claws on anything, office chairs, furniture, carpet, trees, blankets on the bed, sides of the bed. They also climb up the flyscreen doors if they've been outside for a few hours and no one is home...Awful. The flyscreens have been changed but the carpet remains a little scratched. But hey they're just my cats. The dog also scratches the glass sliding door to get in or out as well as our wooden doors for the same reason. We can see fine scratches on most of our doors. He also scratches the flyscreen if he's been locked out. He's had flees but we just give him the standard treatment from the vet and their gone-same goes with the cats. Rarely happens. We have a big family. 5 adults have lived there for over 10 years. People are just coming in and out non-stop throughout the day-7 days a week. Including girlfriends, husbands, boyfriends and mates as you can imagine. Just my experience though. The house needs a lot of TLC.
