I am such a softie....

Good luck with the little one . Same thing happen to me a few years ago. We bought two rats pups and NONE of or snakes wanted them so instead of euthanizing them I hand raised them. It was A LOT of work but totally worth it. I took them to work so I could care for them 24/7. My boss thought I was nuts. And the time went by fast. I missed when they were so little . I think I have a video of them and if I can find it I'll post it.

Keep him warm, either stuff a box full of CareFresh or soft hay or place human heating pad on low beneath his cage. He needs to be in the dark since pups are sensitive to light. KMR brand works well, offer bene-bac or pure yogurt to help digestion. You can buy liquid B-12 and place 1 drop once a day in his KMR to give him a boost if need be. Overall he needs warmth and fed around the clock. Try to introduce to him to baby foods lacking rat toxic items plus solids as soon as possible. If he begins to sneeze or cough you may have a hard time getting him to survive. I use VetRx and childrens cold medicines with my weanlings and adults. I do not know how the VetRX will work on a pup but the childrens cold medicine can be given with his KMR. 1 - 2 drops only.

Hope it works out~

Great advice! I used puppy milk replacement fed with a syringe when I raised my two rap pups though. They were about the size of the OP's and did great on it.

It is very young and the odds are against it.

It has to suckle so you need a really small bottle/nipple. Petco may have it. If not, go to a pharmacy and ask for an infant dropper. You will have to feed it slowly but keep going till it spits up more than it eats. Keep it warm. It needs to eat every 3 hours, even at night.

Now the fun part - You have to stimulate urination with a warm soft cloth. Oh, and don't forget the other opening.

Have fun.

Also, great advice!
