We are right there with you, fighting at least one
pretty scary episode every 7-10 days and minor
episodes another 1 -2x/week.
My cardiologist goes by 4 mg/kg up to 3x/day for the
lasix dosing. My regular vet says 4.4 mg/kg up to
2x/day. Just remember a kg is about 2.2 lbs so divide
Q-tip's weight by 2.2 to figure out how many pounds he
is then multiply by 4 to figure a maximum dose.
For my cat (about 6.6 lbs so 6.6lbs/2.2kg per lb = 3
kg). 3 kg x 4 mg = 12 mg. So I can give 12 mg 3x/day
for a total of 36 mg. Currently Cozette is getting
something like 7.5 mg at 6:30 am, 7.5 mg at 2:30 pm
and 7.5 mg at 10:30 pm. However, if her respirations
are really good (18 to 20) I give her 5 mg, and if
they are elevated (28-32) I give her 10. If they stay
elevated she gets another 5.
We have also added hydrochlorothiazide (HCTZ - without
the spironolactone) to her treatment because sometimes
we can't get her breathing under control even at 35 mg
lasix. We have only been giving about 3 mg of the
HCTZ 1x/day at the 10:30 dose because for whatever
reason, she seems to have problems at night - she will
be fine at 7 pm and at 9 pm, but suddenly at 10 pm her
respirations will be creeping up and after treatment
they start to come down only around 2 am.
Since my kitty has been having some renal issues, I
try to make sure she has plenty to drink. I have two
kitty fountains and if she follows me into the
bathroom or kitchen I let her drink from the sink. . .
Her kidney values have been OK for the past month
despite the larger and larger doses of diuretics. We
are keeping our fingers crossed.
Best to you and the Q-tip.
Nala, Camille and Cozette
