Hey,
My boyfriend and I have noticed that his new Dumerils boa makes this little cracking noise, mostly when she sticks her tongue out. Now I know this COULD be a RI, but i see no other symptoms and it is mostly when she sticks her tongue out so.. i'm thinking maybe she injured herself, because she randomly struck out at nothing in her tank a couple of times, but i'm not sure. I'm also asking the breeder i got her from when she last shed. I really hope it's not a RI :( what do you guys think it could be?
