I have done it, but it's very difficult... the survival rates aren't great at this age and without a mother, and basically you are going to have to feed this thing every 2 to 4 hours, if not more often. Keep it very warm, and I'm sure your vet will provide more instruction. Good luck, and move to NM if you want herps in your backyard... they're plentiful here!
P.S. There may be a reason the mother may have abandoned the kitten... or perhaps she was away hunting when you found it... just some thoughts... Good Luck!
