Don't buy a reptile on impulse.
Lol! I'm more of a 'see a picture of something, research it, and then buy it when i'm not expecting to'.
Like, at a reptile show. I research a lot of animals and don't plan on getting any of them, but oops, just got another one. I think many of us are guilty of this one.
And a must-know for all newbies....
DO NOT thaw out frozen rodents in a microwave... It's not pretty.
