Hi everyone! Happy Valentines Day! You all are never going to believe what Thunderbolt is doing!!! We have two Guinea Pigs (Cinderpiggy and Clementine). Anyway, they are on a stand in a large tank. So, this morning, after living with us for 8 months, I find Thunder sitting on top of the piggies' pigloo inside the tank. Everytime a piggy comes out, WHACK, he cracks them on the head. He is spending a lot of time observing them. I don't think he has any desire to eat them. So then I put a baby gate on top of the tank. So what does the little buger do? I find him laying on top of the baby gate with him arm stretching in the tank, and WHACK he is cracking them on the head. Any advise?
