We had noticed she was suddenly struggling to breathe, wasn't eating, wasn't drinking, nor would she lay in her normal spots.source ↗

My question to anyone dealing with or has dealt with this. How did it/is it going? I'm scared for her.source ↗

My girl is 12 years old and recently diagnosed with histoplasmosis. Unfortunately it was probably there longer than we knew because it has already caused blindness in one eye. She sees the vet again tomorrow to start anti fungal treatment. Has anyone else dealt with this in an older cat? Did your cat eventually recover? Trying to have realistic expectations but pretty worried.source ↗

I will spend whatever I need to spend on my baby, I just can’t imagine being faced with having to choose to put her down or not.source ↗
