I have only one Cheerio.
At our house we get our friends as rescues, there are a lot of unwanted animals out there.
Our snake's supplies were listed on Craigslist for $30. My wife wanted a reptile and contacted the man. Turned out that he still had the snake, his son "left" her to him when he went off to school. The man's plans were to release her in a nearby refuge. I'm pretty sure that's illegal but it became a moot point as my wife came back with viv, hides, UTH, and SNAKEY.
If I get another it would be nice if I could give a home to an "unwanted" animal, but he photos section on this site is changing my mind about only having rescues.
It was a space thing at first. Cheerio's viv is huge, 54" wide X 58" tall. It takes up some space in our rather small home. Recently I've been thinking that the bottom, which is two large doors with shelves, could be opened and remade into two smaller vivs. That is an example of how frequenting this website gets you thinking "you know, I COULD get more snakes".
