I have 2 guinea pigs named Hazel and Nut. They both are very loud piggies and they always popcorned. Earlier, I noticed Nut wasn't acting normal. He was usually very loud and would always wheak but I often saw him hide and wasn't in the mood to play. He still eats the hay, pellets, and veggies i give them. I also noticed he was completely ignoring me when I call them for food. Nut usually came running to me when I call them but he doesn't seem to hear me. I need to confirm whether he's deaf or is he just going through a phase? xoxo
