Pee pee carpet from previous tenants or owners

[Jennifer Cross]

My family and I just moved into a lovely home we are renting.  The only thing we can't stand is the carpet.  The landlord bought the house before we moved in.  The previous owners "professionally" cleaned the carpets which are stained and smell like pee.  The landlord has hired 2 different carpet cleaning companies and still no luck.  If he refuses to replace the carpet and padding what can I do as a tenant in Texas?
