Can I evict for non payment of pet deposit?

[Vickie Bruce]

I rented my moms house after she passed to 2 young men.  Rent is 900.00 per month.  After they moved in they moved another person in so rent would only cost 300.00 each per month.  Next they brought 2 dogs without saying anything and lease says NO PETS  unless agreed by landlord and 300.00 deposit per pet.  One tenant paid his pet deposit but the other will not.  He first said he wouldnt pay because he lost his job and needed to get another so I gave him 30 days to pay pet deposit.  When 30 days was up he said he would not pay because he didnt have money.  I told him he could pay out pet deposit at 50.00 per month.  He said then he would move but wanted 300.00 of rent back first.  Can I evict for this?
