The last visit to the vet, the vet said everything was ok. He was a little fat. That was less than a month ago. Since we got him he has been a finicky eater. He was eating mice, the only thing he would take. Recently tried him again on a rat pup. Amazingly, he ate the silly thing! So he is now eating rat pups every week. I didn't know they weren't climbers as he climbs on everything put in his cage. His cage doesn't have heating at this point as we're primarily proccupied with trying to keep him cool in a 100 degree plus house. His lighting is a UVA/UVB bulb; 12 on, 12 off. He has an igloo that has a wet cloth on it for coolness and humidity. There is a frozen water bottle changed everyday. His water dish has moss around it for humidity. There is a climbing branch. The cage is glass and came with the snake. He gets baths every day to make sure he is getting enough humidity. We ultimately hope to get him a Boaphile. We are trying to raise him similar to our redtailed boa, but are learning many differences in the two different species. (Duh!) Our redtailed boa was larger at 1 year, too, but I thought, well...
