Make that:
Milk composition table, in percentages, from Borden, Inc. research:
Species--------Solids-------Fat-------Protein------Carbohydrates
Cow-----------11.9----------3.5-------3.0-----------4.6
Dog------------24.0--------10.5-------7.9-----------3.8
Cat------------20.0----------6.5-------9.0-----------6.8
Gray Squirrel-----6.6--------12.6--------9.2----------3.4
That is from this website:
http://www.naturalhorsetrim.com/18.htm It also has racoon, oppossum, rabbit etc, for anyone who is rehabbing those
That should read better. As you can see, cat and squirrel are very close. Just add a little heavy cream or multi-milk and you've got good squirrly formula.
Gabe has a slightly different chart, and surmised this one might be a bit outdated (or reseach varies?) but this is close enough to gie a good picture of what you're feeding with each form of milk.
