I've got a baby grey squirrel, I believe about 5 weeks old, maybe 6? We don't know what happened to the mom, but we watched as what seemed to be a sibling was killed by a crow across the street unable to do anything. Then this cutie showed up at our back door! We tried looking for mom. We didn't see a fallen nest or anything. There was a nearby squirrel watching so we guided him that way and walked away, but said squirrel did not seem happy to see him and left. He's very sweet. We put him in a box with a heating pad and an old robe. As odd as this is, I've given him breast milk for now until I can go to the store later today and get the esbilac. gave him a little apple chunk which he also enjoyed, but mostly played with. I'm hoping there is someone near me that can take him over. I'm definitely no pro. He seems to be healthy, has no obvious physical issues. **side note, I immediately realized that dish with milk was idiotic and removed it. Feeding him with a syringe!**
