I don't know if I've ever seen a reptile that enjoyed a good ol' belly rub, so I thought this was pretty interesting... and cute!
YouTube Description: Baby Mali uromastyx wants her belly rubbed. Every time you open her cage and wiggle your fingers she comes running, flips on her back and waves her arms around while you scratch her tummy. Cutest thing ever!!!
If you're like me and had never heard of the Mali Uromastyx, Wikipedia says they're reptiles that are more commonly known as spiny-tailed lizards.
