I rescued two 4 week old squirrels (one male and one female). They have been on Fox Valley formula and are eating veggies/fruit, protein blocks and still taking formula. She holds her food in her hands and sits upright when eating blocks and food. He won't sit upright, he bends over and eats it, not picking it up. He still drinks way more formula than she does. He seems perfectly active and healthy. Is this normal?
