Up until today I have had no problem keeping the humidity up but all of the sudden it drops to 30% 20 minutes after spraying. They are both panthers. One 6 month old ambi. and 3 month nosy. Any pics of how you do it or tips???
Without any information I would say use a room humidifier. Those are panthers so don't bring the humidity to 80% and leave it up that high. Damp towels on the outsides of the cage will also help quite a bit.
Do you have any water crystals? If so, hydrate some, put them in a wet terracotta pot and put that in the cage (I put fabric netting over mine, it makes it easier to move about without dumping anything). You can pile it up like an ice cream cone. You can "rewet" it by soaking it overnight in water.
What I did was I sprayed around my room and put a large bowl of water out and let it evaporate. That really raised the humidity up in my room about 20%. But it would be easier just to get a humidifier.
