Hey guys its my first time posting on here and i need some help! i had 6 guinea pigs in 2 seperate cages and after one passed away (5 years old) i got 2 babies for my male as he was lonely. Shortly after he got an eye infection and a runny nose, went to the vets and got some antibiotics and it cleared the infection but he was still becoming weaker and losing more weight and fur. Another trip to the vets and i was told there must be an underlying issue here, we tried more antibiotics but after a month of fighting he sadly passed away. Now its been another month and i just got back from a weeks trip where i had a friend taking care of my guinea pigs and she let me know that one of my other girls (in the separate cage) didnt seem herself and wasnt eating. I got home yesterday and she was weak and couldnt walk properly, in the same state as my male. Took her to the vets but they were absolutely useless and told me everything was fine and just gave her some antibiotics after hardly checking her over. She passed away less than an hour later, she was only 2 years old. I have another guinea pig who is starting to go down the same path so it must be contagious and I'm very worried about her, and my other guinea pigs getting it. The vets aren't being much help so i was wondering if any of you guys have any idea what could be going on, sorry for the long post thank you
