They dig holes on your dry wall, chew stuffs, scratch up the floor, and the worst, urinating on the floor or carpet (you will have to replace the whole flooring to get rid of the smell).

We use the following protocol on a unit that we suspect pet damage and we will require evidence in case of court, i.e, pictures.When we do the move out inspection we will pull any area of carpet back to reveal stains on the backing from pet urine that the resident denies they had.

She also left a couch that was literally soaked in dog urine and her little male dog had marked up the whole place. 

The problem with carpet pad in a rental is that it holds/traps liquid (water, soft drinks, beer, pet urine) that the idiot tenants are not smart enough to clean up.

Also if you allow pets it's a no brainer to get rid of the carpet since the urine smell never goes away when it gets down into the padding, but with vinyl that's easy cleanup. 

Pet urine?

It will also pay enough to replace dog urine soaked carpet and particle board in a master bedroom of another house and there is change left over. 

Brought 3 dogs instead of 2, didn't pay pet deposit on move in, dogs peed in the back room (the flooring we have to replace), and they covered it with perfume, but if you get down at floor level to take pics of the swollen corners and edges from the pee, you're hit with dirty dog/urine smell. 

What do you recommend for cats that urine in closet and get behind the the trim/drywall? 

Just google eviction service near me.It is pretty normal for the new owner to deal with that; the only way I have been able to get around it is by making the EMD non-refundable, which gives the seller confidence you will close or at least let them keep the EMD for damages.In terms of the pet smell, order a 40yard dumpster and get everything out, next any good PM can hook you up with an enzyme spray treatment that will metabolize the pet urin.
