Baby squirrel losing weight, constipated. What should I feed it?

Thanks for reaching out. Rodents are difficult to hand rear as their milk has a much different conformation that cow's. Hand rearing has been more successful utilizing goat's milk with whipping cream (high fat content). The pedialyte might be diluting nutrients to where not enough calories are being delivered. This is hard. Good luck.

Thanks for reaching out about your new squirrel. Green diarrhea is often a clinical sign of liver disease or mal-absorption problem. Cow's milk is not appropriate for rodents but not much else commercially available. If there a wildlife-rehabilitation society locally that can give some assistance? They might have an appropriate milk replacer. Good luck.

The PediaLyte should be used for hydration, then switch to the Esbilac. Overfeeding can cause diarrhea. You can give a tiny bit of Bene-Bac or plain yogurt to promote a healthy gut. Consider consulting with a wildlife rehabilitator or wildlife veterinarian. Check local laws to make sure you can keep and raise Bo.

Puppy milk is most often use to bottle feed little squirrels. You can get it from a pet shop or from your local vet. You need to get a bottle for bottle feeding (sometimes you can get a whole kit which contain milk and a bottle). Then you need to follow feeding instruction that you will find on the milk.

Lowfat cow's milk does not have the appropriate nutrition profile for baby mammals. I recommend kitten milk replacer. If you do not have access to kitten formula, you can make a homemade formula: 1/2 cup whole milk 1 egg yolk 1 drop pet multi-vitamin 3 crushed Tums (antacid) Mix in a blender and replace every 2-3 days. This homemade formula should only be used until a balanced pet formula can be obtained.

I am sorry to hear about Potol. It sounds like he is in need of urgent veterinary care. If he is weak and not eating he is likely very dehydrated and may need aggressive supportive care such as fluids given under the skin on via a vein. The vet will need to examine him and get a history to try to determine why he is not eating to address the underlying problem.

Getting this baby to a wildlife rehabilitation facility if best. That will give her the best chance at survival. You can refer to this care sheet for raising an orphan squirrel while you look for a rehab facility. ( https://www.whatdosquirrelseat.org/baby-squirrel/ )
