Hi my name is Kristina and i have a 2 1/2 year old guinea pig named roscoe! i'm going to be honest, i became a member to ask questions regarding his health! Tuesday night i started to notice a change in his behavior. I brought out his normal plate of veggies that he usually loves and he didnt greet me by my bed when i came in. He stayed sleeping in his pigloo. I immediately became worried. Then I noticed he was not pooping, let alone eating or drinking anything. That night all he would eat was the veggies. I had to force him to drink water. Yesterday I took him to his vet (exotic specialist). She ran some tests and said everything came back fine! She said his teeth looked perfect, lungs were fine, nose and heart were good, etc. The only thing she found in the tests was hair when she reached in to get an intestine sample. She said she thinks he has a hairball and it is blocking him from pooping. She put him on Bene Bac Small Mammal Gel to help his digestive system (once every 24 hours), and Emiraid Herbivore (force feeding formula) to keep up his nutrients. I brought him home yesterday and gave him the formula and gel and he still would only eat his veggies. He would not touch his hay and would only pick at his guinea pig pellet food. This morning, I woke up to find some small poops!! They were runny but hey, it was poop! I gave him his gel again and bought a brand new bag of hay and even new guinea pig pellet food at the store. He picked at some of the hay and pellet food and then went to sleep. He still mostly takes to lettuce and his veggies and actually cleans the plate! He has pooped but they have been small and quite soft. What is going on here?! Is there something I am doing wrong??? Am I going to lose him sooner than I think!? I am so confused and his behavior is different as well! there is no popcorning and making squeaks when I bring out food. I feel helpless Any answers would be much appreciated!!! Thank you soooo much
