We have two prairie dogs - a male & a female- that we've had for just over a year. We are now having a HORRIBLE indoor fly problem that seems to be originating from their cage. Their cage is cleaned several times a week, but we still cannot get rid of the flies. This has been going on for several months now. It is disgusting and has gotten so bad that we are considering re-homing our sweet little babies! Has anyone else had this problem and if so, what worked?
