hii, today my guinea pig fifi very unexpectedly and suddenly crossed the rainbow bridge. since then, gingernut hadn’t moved. i thought this was due to grief because they were close but when i went to see her, her back area was very floppy. her back legs look almost paralyzed and she cant walk, she drags herself with her front paws. her eyes look cloudier than usual and her body’s getting cold and vibrating a lot. shes eating (less), drinking (less), peeing and pooping and still has her curiosity and liveliness but less than usual. shes very lethargic and wont move (unless for food) from where shes laying after peeing or pooing so I'm cleaning it regularly to prevent infection. i also gave her willow which is a natural painkiller and arnica oil on her back area as well as arnica homeopathie. shes been improving since then which is great. i took her to the vets this afternoon too but he wasn’t a specialist, only saw her since it was an emergency. he couldnt give me a diagnosis because frankly he wasnt sure what he was doing. he did give reasonable suggestions though such as a fall or bacterial infection but their cage has been very clean and she couldnt have fallen from anywhere. I'm also really weirded out by fifi’s sudden death on the same day. fifi was’t feeling great about a month ago (general symptoms, lethargy, less appetite etc) but the vet said there was nothing wrong with her and she went quickly back to normal, although not as active but i think thats her age. i have 3 more guinea pigs but they all seem happy and healthy. I'm trying to get hold of an exotic vet but its difficult in my area. in the meanwhile, could anyone please advise me on what it could potentially be and how i can help gingernut? at the moment shes in a seperate cage wrapped in blankets with hay, veggies (high in vit c for her immune system) and water as well as willow. thank you xx
