I agree with the idea of letting them stay, adding the pet deposit and socking the money away because in the end, this can be a challenge to take care of the odor.On the other hand, if the contractor is not used to cats even one dirty litter box can cause a significant ammonia odor (cats consume a very high protein diet and thus produce a high urea content urine).

I agree with Paul that the LR REIA is an excellent group.
