I know that Cheryl at Rio Reptiles/Beardeddragons.co has them occasionally, and I believe Carolina Classic Dragons has one for sale on their website right now. There are several big companies that have them frequently as well (like LLL Reptile and Reptmart).
Mirage came out of brumation on April 26. He was doing great. On May 2 he started acting funny. We just redid his tank, and he keeps going into one of his hides. He just lays there. He shows no intrest in food. HELP!
