I recently purchased 2 new garters.
One is inquisitive and healthy and the other has me concerned.
Perhaps you can provide assistance and let me know what to do.

Emily appears to be getting weaker by the day. She has been the more demure of the two since I received her 3 weeks ago. She eats some, but not nearly as often as the other. I do feed them individually.

Today I noticed that at times she has her mouth open every now and then. It looks similar to a dog panting, but she's not panting,

It also appears she has lost weight and doesn't show much interest in her surroundings.

Your help is greatly appreciated..........Bob
