Phew!!! Glad to hear no broken bones and the injuries seem minimal.
I gotta say, feeding a snake daily sounds like an odd Rx to me. But I'm no vet.
I personally wouldnt stray from the vets regiment though, because I would fear dosing the snake directly may alter the medication's dosage strength and cause more harm than good.
I wouldn't hesitate to call the vet back though if Peaches refuses the food, because of course now she wouldn't be getting her meds.
Anyway, great job getting her to the vet quickly and getting her on the road to recovery. She's lucky to have you!!
...just find yourself a better snake sitter moving forward, hahahaha.
