Here is a protocol developed by Duckman, one of our most dedicated, knowledgeable and greatly respected members. I have edited this a bit from his original post for readability but will include the link below to the original thread that contains the post.
This is used on pinkies, which is where the 32/40 issue gets encountered most frequently. Since your guy is 4 weeks, you may need to tweak this protocol... but in essence it is all about breaking up the sludge / cement of the 32/40 in the babies stomach. The solution is dilution.
We do not recommend 32/40 for squirrels. Period!
The trick seems to be getting in as much water, as quickly as possible, once you see and feel the hardness in the belly. Not sugar water or Pedialyte, but
plain water.
Do this every hour (giving about 0.2ml-0.3 ml) and ensure you stimulate after each, for 2 reasons:
1. You have to get that water out of the bladder, and it will burst if you don't.
2. You want that water to start working on the crud in the belly.
After 8-10 hours, you should start seeing some movement out of the bowel (they will continue to poop, but you will start to see it more watery, which is what you want). At that time, start introducing diluted formula at the ratio of 25% Esbilac, 75% water. Feed this for the first half day.
The second half day, bump up the ration to 50% Esbilac, 50% water 50/50.
Third day move to 75% Esbilac, 25% water.
Fourth day go to full strength formula; the blockage should be gone!
So far, Duckman has had tremendous success with this protocol and others that have followed are getting great results as well. One note of caution: Check my pinkies after every feeding, so see if their bellies are hard or squishy. It is suggested everyone get in the habit of checking them after every feeding as habit and you can't go wrong in catching them before they bloat up. Once they take on that angry red color on their bellies (this is when their system goes septic), they are gone and can't be saved, so the trick is to catch them before this happens (hence, getting in the habit to see if their tummies are hard or not).
