My 4 month old fox squirrel’s behavior has changed. She had been climbing and playing on her cat tower and even climbing to the top to sleep in her backpack. She has always willingly let me pick her up but the past two days she has been walking in circles nonstop and runs from me when I try to pick her up. When I first got her, She was found on the ground at about a week old. I received a lot of advice on diet for her when all the scary stuff was released about Esbilac formula. I don’t know if she has issues due to her fall or the formula she was given her first two weeks. She has always had some issues on her left side and has zero balance. She has always veered left when walking and falls to her left. When she holds her food sitting up on her haunches, she tips over. This has been her normal but not the nonstop circling. Any ideas???
