Will not eat!

[jimpmc]

Hi,

We have had a red-tailed boa for three years. She has eaten regularly (thawed frozen rats) and without problem until last November. Since that time she has refused to eat at all. We have tried giving her 7 different rats since November. She did shed in January, but still has not shown an interest in anything. We have tried several things -- moving her next to a radiator, adding more heat lamps...I've even tried dangling a rat around to get her to notice it. She is mobile and active otherwise, but passes right over the rat.

Any suggestions? Should I be concerned at this point?

Thanks
