I noticed that my little beardie(although not really that little anymore bout 8' -8 1/2' inches) is becoming less active and more lethargic. He definitely outgrown his cage but also i give him less frequent baths and play time. Would he feel better with just having more play time and baths(he does drink from his water in the water bowl inside his cage though) or do i really need to buy a 40g cage asap? p.s he has only been this way for a week but im worried abut him... Please Help Thank you
