My daughter had two guinea pigs for about 2 years. Unfortunately one of them died in Nov. after he had teeth work done. My daughter recently went off to college and I am now Mom of Zero (2)and Mashi. Mashi is only about 7 weeks ago. I got him last week and every thing seemed fine, he was very active eating and drinking like crazy and LOVES to be held. He had his first vet appointment last week for pink eye unfortunately the vet that was able to see him that day didn't know much about piggies. (I brought him in thinking he may have a cold) Any ways I noticed yesterday he wasn't as active he just kind of sits around. I have seen him eat and drink but not NEARLY as much as the first few days. I just assumed after all the excitement he was having a lazy day yesterday. Well today hes acting the same, he just sits in one spot for long periods of times. His appetite has decreased and so has his water consumption. I will be taking him to a vet tomorrow that specializes in small animals but Im really concerned. Could he be sick? I also noticed he breaths kind of fast. I have never had guinea pigs so Im not sure if that is normal for such a small baby. (he is 10 ozs) We have all fallen deeply in love with Mashi and Zero bonded with him right away. Could he be sick or is this normal behavior for a baby? I held him near my ears yesterday and didn't ear any wheezing he has sneezed a couple of times but nothing serious. The other day when I woke up he squeaked as if he knew it was time to eat, today he is also not very talkative even when Zero gets too close to him and rumbles. He just sits there like a huge cotton ball. When I got him he was kind of skinny but I can tell he has put on weight. I will be buying a scale tomorrow as well. Our other piggies Zero and our deceased king were never really into being picked up. My daughter never really worked on that. Though the other day she came home to meet Mashi she was able to pick up Zero, he literally plopped down in her arms and fell asleep. Just worried Mashi is the sweetest Guineaa pig but starting to wonder if the reason he is so sweet and cuddly is because hes sick..... sorry just started to ramble lol.
