I have two boys a little over a year old. They are both skittish for no reason (it happened out of nowhere, they were never like this). They hardly move and are scared of exploring their cage. They eat fine but I haven't seen them drink water at all lately when before they used to always drink. I tried placing bowls of water for them but they aren't drinking that either. I haven't added any new items that haven't been there since they've been with me. Most of the time now, they just stay in one spot.
