22-year old southwestern gopher not eating

[Randie]

For most of her life, she has eaten thawed (previously frozen) mice and rats every 2 weeks. In recent years she refused rats, and I decreased the rodents in size over time, until lately she eats only adult mice. But since January she has refused all but 15 adult mice total. (10 in Jan, 3 in Feb, 2 in March, none in April).

In the last week, she was pretty active in her enclosure - out of her hide, moving around and scenting a lot. I thought she was hungry, put her into her feeding tub, but she showed no interest in the mouse. I have tried holding the (dead) prey and moving it, and leaving it with her in the feeding tub for a couple of hours.

Her enclosure temperature is ~ 68 F at night and ~77 F during the day. I mist it regularly. About 1.5 weeks ago she shed (incomplete, but I gave her a warm water bath that removed most of it)

Would love any thoughts, suggestions ... Thank you!
