He’s 5 months old and it has been 4 weeks since he’s really gone to the bathroom. There was a tiny bit the other day but very little and very dry. I took him to the vet again. They x-rayed, gave him laxative and more dewormer. I got a new reptisun T5HO terrarium hood and bulb but I’m still confused about this light. It does not replace his heat lamp correct? Just the other bulb that is on when it’s not. I need some clarification, someone please help. Also do I just sit it on his terrarium cover? It does not have s as way to mount it.
