It’s been just 24 hours and the difference in his coat is amazing. His fur is already starting to grow back. I guess those mites just needed a harder kick in the patootie.
In order to help Rex put on some healthy weight, I’ve started giving him a tiny bit of Nutrical each day (for the extra calories), 2-3 black oil sunflower seeds (for the good fats), and a show-quality rabbit food (‘extruded’ to maximize nutrient absorption). It turns out that Scully LOVES the show food and has tried moseying up to Rex in order to share his dinner. I’ll be keeping a close eye on her…
Haven’t heard from the vet with the blood panel results, so we’re just waiting and hoping that no news is good news.

I’m happy Rex is responding so rapidly to the TLC you’re giving him. :-D
Scully, you be nice to Rexie, and let him have his special food!
Poor Rex! Your plan sounds good. Where did you get the show quality food?
