We have 2 Guinea pigs... both boys. And they have been healthy and easy to care for for years. They are 3 1/2 now. But we noticed one of them was losing weight and not running out when we brought the veggie treats outs. We took him to the vet who was familiar with small animals, but not an expert with guinea pigs. Our pig, Mojo, only weighed 20 ounces, down from probably 40 ounces. The vet xrayed him, checked his teeth, clipped his nails. According to the x-ray, his stomach lining was inflamed. She gave us antibiotic and we started hand feeding him Oxbow Critical Care a few times a day. It took probably 5 days, but then he started showing some interest in his food. But he still didn't want to move around much. I bought him a bed and apparently he just layed in it and peed because he was wet when I picked him up. What I didn't know was that the bed wasn't wicking any moisture away from him and he got urine scald...And then I noticed red sores on his pads. The Vet gave us a special wash to clean his paws twice a day and showed us how to cover the back paws with bandaids to protect them. So I have been hand feeding (supplementing) him, and cleaning and bandaging him twice a day for about 6-8 weeks. He gets a clean fleece pad twice a day to sleep on, and the whole cage has fleece on the bottom. At one point he also had soft stool (presumably from antibiotic), then got a respiratory infection (more antibiotic) and the last visit to the vet she heard a heart murmur. He is eating, and gaining weight (he is up to almost 29 ounces and does eat well, but now his back paws are swelling up as well as having these scabby sores on them. And he is not wanting to walk much again. I am encouraged that in some ways he seems to be improving, but this has been going on for sooo long. Is this normal for recovery to take this long? What else can we do to help him? Where is the magic pill or ointment that will fix this? I don't want him to suffer, and this is getting old, but he has too much life in him to put him down. I guess his entire health is so fragile he is susceptible to anything and everything. Any suggestions would be appreciated.
