Adopted guinea pig, under a year old. Sometimes he spins but in a smaller cage its not often. Ruled out inner ear infections no ringworm possibly nuerological. I brought him home from the hospital today and he has been mouthing his water bottle for the past 10 minutes. But he has been eating and drinking well and passing his bowels. He has never been fed veggies so I was wondering if I should slowly introduce them as to not upset his intestinal flora or just start daily greens. I have him a small quarter piece of a carrot today. Thank you!
