That's Dexter he's doing fine many years later.
Appreciate the quick response. I am just sad he is having issue. I've posted a couple times about him, following all recommendations. I put so much time into feeding feeders, his setup, and feel like I failed him. Ugh! Praying the shot works and the new schedule of A on feeders is the solution.
