OP what does your lease state about pets? And was the notice given verbally or in writing?

Based on OP's post history he's in California. So, some reading for him:

If you've been in your place long enough to go month-to-month, offer to be out in 30 days instead of going through the court eviction process, which would take your landlord just as long anyway. It would keep an eviction off your credit report and give you more time to find a new place.
