What is best test to confirm cat urine in carpet?

[Guest guest]

Hi, everyone -

I just had a visit from my landlord and the property manager of my

rental house because I have complained of cat urine in the carpets.

There is also some chemical that was used by the former tenant to

either remove or cover the ammonia odor and the chemical is making me

sick. I have been complaining to the property manager Since 11/9/11

but he refuses to accept that the former tenant's cats peed all over

the house. I did purchase a UV

light and it showed urine stains all over the house, then I hired a

professional photographer to take clear photos of the stains under the

UV light. We are going to move out of this house soon and I

anticipate some kind of legal difficulties because I am going to have

to break the lease, so I need to ask for suggestions.

What is the best method to test for urine in the carpet? Do I need to

hire an indoor air quality professional to take carpet fiber samples

and have them tested in a lab? While the cat urine photos are very

good, I don't think they are the concrete evidence I need, so any

suggestions of who to hire and how to get concrete confirmation of

urine in the carpets would be most welcome.

Thanks so much.
