Thank you for your concern. I think we are leaning toward a corn snake or two. Can we have more then one in a cage?
We already have a 40gal reptile cage (the glass tanks with the locking screen top) that we plan to use. We also have a Habi-Scape Rock backgrounds for the back wall, unused draft wood, unused ghost wood, an unused wooded half log hiding area, reptile lighting/heating unit and the temp and humity gauges. (all the wood has been gotten from pet stores and is treated) The ideal plans are to add some plants, rocks, the wood pieces, a water area, etc. For bedding I was thinking of using the same as we use for the frogs.. a mixture of the Bed-a-beast, peat moss and wood chips.. does this sounds ok? All plants I would use will be from reptile approved. Also would it be ok to have some moss growing on the ground?
We have talked about the need to feed a snake mice/rats or even larger aminals. Everyone in our family is ok with this. We have had many differnet types of pets currently and in the past. My youngest son Dante' has 3 pet mice and we have had pet rats years ago. We have also had Geckos that ate pinky and fuzzy mice, when laying eggs. Our White Tree Frogs get pinky's as a treat once in a while. One of our friends has a couple ball pythons that my oldest son Sebastian (he wants the snake) has cared for when they leave town. And today he came home with a common baby ground snake that he caught. (after showing us, he took it back to were he found it and let it go) So he is very comfortable handling any size of snake. As is my youngest son, my husband and myself. And yes we know the cautions of handling the mice and snake. Key rule.. ALWAYS WASH YOUR HANDS BEFORE AND AFTER HANDLING ANY ANIMAL. In the past, both my husband and I have been involved in reptile rescue, mostly Iguanas.
And last but not least... the vet bills. We are not worried about that. Our pets are part of our family, no matter what. We do have a vet here in the area that specialist is reptiles. Trust me I think I am one of the few people who would pay a $350 vet bill to care for a pet feeder mice...lol. But the animals well being and my childrens happyness was worth the money in the end.
Please keep in mind our rules are that before any new pet is allowed in the home, we most do research and learn the needs of the animal, make sure we can give it the best home possable. There is also a waiting period of at least 6 months to a year to in sure it isn't just an at the moment phase. Once the research and waiting time is over we set up the environment and keep it stable for at least 30 days before we get the animal. This is to in sure the temp levels, plant growth, etc are stable. So far Sebastian has been asking for a snake for almost a year, has gotten himself a few books on snakes and their care and has been saving his money.
I hope that helps at least a little.
