I'll be happy to give you instructions (it's really good to know anyway!) but for right now, try feeding the normal way, that's always preferable. And many snakes
undergoing medical care (injections or oral meds) aren't going to eat anyway...so don't be shocked...and if they do, they might toss it back up, depending on what
the med. is- did the vet suggest you feed on schedule or wait?
Rotten luck, two snakes needing extra care at the same time...
