Good for you! Not easy. We've been giving our 17 year old Siamese cat Beeper subq twice a week since October, and it's keeping her kidneys (polycystic kidney disease) stable so far. She hates it, but it's quick. Sometimes they throw up after subq--our vet thinks it's because of some momentary vascular response to getting fluid--and that kind of throwing up is not something to worry about, she says. Anyway, the subq really does help.
