I've never heard of an apartment complex doing monthy checks. I take it they have a no-pet policy? I guess you could get a rack on wheels and move it when they come check, but it would be better to try to come to some agreement with them or find a new apartment. Keeping pets hidden is never a good idea. I wanted to get a BP 4 years ago, but the apartment I was living wouldn't allow it. If you decide to hide them just be careful.
