Today I purchased a baby Tiger Rat snake. Generally speaking males reach sizes of 10' where as females reach about 8'. The breeder whom I bought it off suggested that I get something with the dimentions 4' x 2' x 3' for when it reaches adult hood. I havn't recieved the snake yet, they are only 1 week old and the guy wants to make sure they are feeding well before he brings me the snake, but when I get it I'm going to keep it in a 2' x 2' x 3' aquarium, which will be more than enough for its first year. However when it gets larger I'm going to need a larger more easily accessable cage for it. 4 foot deep would be awful hard to reach down in to clean out a tank. So what I'm wondering is if any of you guys have ever built an enclosure for a large aboreal snake or if its just as cost effective to buy one for it. I've got a while untill the time comes that it needs a larger tank, but I'm thinking ahead, and may just go ahead now and put the little guy, who will probably be around 2' long when I get him, in a large cage.
