100 syringes = $17.49 (Monoject 3/10cc with half unit marks)
100 lancets = $1.49 (Invacare)
100 test strips = $33 (Maxima AST)
Insulin - from Walmart in Ontario - LEVEMIR (doesn't poop out as fast as Lantus)
$120 for 5-pack of 3ml cartridges -- we are able to use to the last drop (3-4 months each)
I have two diabetic cats:
Rusty avg 1.5u per day
Tiggy avg 1u per day
for both, one cartridge $24 lasts approx 120 days or 4 months -- lets say 3 mo to be conservative === $8 per month
so... syringes, lancets, test strips
per cat per shot = $0.52 (not including insulin)
per cat per day = $1.04
per cat per month = $31.20
extra tests - lancet + test strip .015+.33
$0.345 per test
estimate 6 extra tests per week per cat:
$2.07
per month (4 wks)
$8.28
So...
$ 8 insulin (both cats)
$31.20 per cat
$ 8.28 per cat
=====
$47.48 per cat (except insulin is for both)
My two-cat expenses: (not including food)
$86.96
For food, I feed canned Wellness and have 5 cats, so I won't bother computing it.
