Junior Guinea Pig
Thanks @Freela your kind words mean a lot. I feel so bad seeing her suffer and wish there was more I could do. As sad as I am about what's been has found though, it's weirdly a relief to know what the problem is at last. My vet's also been pretty optimistic that it can be managed so I've just got everything crossed that we find the right combination of meds for her soon.
