I have 6 red-eared sliders that were my husband's, that he kept in a pre-formed pond outside & brought them inside in a stock pond in the basement for the winter. My husband passed away, & I have MS and am unable to do the work needed to care for them. They have never hibernated so I am unsure if they will ever be able to. The ages are approximately 10 down to 3'ish. I feel really bad, but not much of a choice & it's getting pretty cold.
