Oh Jasper, honey, please eat for Mommy!!!
Jen, maybe the Nutri-Cal will sustain him for a while until his cold clears up. I know how overwhelmed you can become and I've overlooked some of the simple remedies like Nutri-Cal before as well! I've had to smear it all over poor kitties before to get it in them! I've also syringe-fed the liquid from water packed tuna! It's basically just tuna flavored water! Maybe you can try that too.

Hang in there!

Hugs,
Kim
