Help with Neotoma floridana baby

Question
Hi,
We burned pasture and a baby packrat/woodrat/neotoma ran out of a nest.  I couldn't stand to leave it and have been feeding it KMR since Sunday.  It has opened its eyes now and I am worried that milk is not enough, but he doesn't seem interested in solids.  I've put tiny pieces of almonds, peanuts, cereal in with him too.  He developed diarrhea today and was given LRS and Baytril (husband is a vet). Can you tell me if I'm on the right track or what I should do different?  I haven't been able to figure out what his normal diet should be in captivity.  Any help/advice is greatly appreciated. Thanks so much.
Tracy

Answer
Bushy-tailed woodrats eat lots of woody vegetation, and in drier habitats also concentrate on succulents(cacti). This species gets all of its water from its food and does not need to drink. Woodrats tend to eat plant materials which have high concentrations of defensive chemicals; they combat these defenses by eating only small amounts of each species. Neotoma cinerea also tends to eat low-energy food items and plants which are high in oxalates. This has implications for the building of middens, discussed below. Neotoma cinerea has an enlarged caecum, and engages in coprophagy.

I got this from a website.  I have no experience with this species.
Such for Neotoma on the internet
