Thank you for taking the time to post a reply.
There hasn't been anything unusual happen lately that I can think of. Same food, same everything, no guests at all. She still plays when she comes out, but she hasn't really been coming out voluntarily.
I think that she just may have swallowed something she shouldn't have. She licks practically everything and has eaten a string before. (see: http://www.angelfire.com/80s/pestosw...pictures3.html )
Anyway, she has spent much of this evening with us, so I will give it a day or two and see how she is.
Thank you again.
