It will depend somewhat on the insulin your vet wants you to use, but if you can get a script for Lantus or Levemir (two of the best insulins for cats!), you can buy your insulin from Canada and save quite a lot!
A 5 pack of either will run about $200 but that's 1500 units which is enough to last most cats at least a year!
Here's the
info on Buying insulin from Canada
Most of us here use the Relion Confirm or Micro blood glucose meters from WalMart…..there's absolutely no reason you need to use a "pet" meter so don't let your vet convince you that you need one! All our dosing methods here are based on using human meters anyway so we're very comfortable with them.
The meter is about $15 and the strips are $35.88/100 for both the Confirm and the Micro. They take the tiniest sample size which is important when you're new to home testing. Later on, if you want to save even more, you can go with the Relion Prime ($9 for 50 strips) but the Prime takes a larger sample size.
Lancets are anywhere from about $2 to $15 for a box of 100.....and it doesn't matter what brand you use! All lancets are are pieces of plastic with a sharp metal point used to poke the edge of the ear to get a blood sample.
Some people like having a lancet device, but most of us just freehand it. If you want a device, it's another about $5
Syringes will also depend on the insulin, but
ADW has both U100 and U40 syringes at reasonable prices ($12-$30 per 100)
Now for food....there is NO reason to spend money on "prescription" food! Most of it is garbage. The ingredients are lousy and they are too high in carbohydrates for a diabetic cat. Most of us feed plain old Fancy Feast Classics, Friskies pates or 9-Lives ground, but there are lots of choices!

Keep asking questions and God Bless you for considering adoption an "extra sweet" kitty!! You will never regret it!! The bond you form with your sugarcat is so much more special because they depend on you so much...and they are so happy to repay your kindness!!
