Welcome Amanda! I'm happy to see you over here from the Facebook group!
Treating diabetes does not have to cost a fortune! First, getting Juicy onto a low carb canned diet may bring her numbers down quite a bit (up to 200 points!) Also, the stress of being at the vet can also raise it considerably (up to another 200!)....add an infection and her glucose levels could be sky high! So even if her levels were really high at the vet, they could be much lower at home when any infection is cleared up and she's eating a low carb food
You can start learning to home test now and see what the diet change can do. The Relion Prime is available at WalMart for $9, a box of 100 strips is $17.88 and you can get lancets for anywhere between about $2-$10 depending on brand.
One of the best insulin's for cat's is Glargine (brand name Lantus or Basaglar) which you can buy from Canada for 1/3 to 1/2 the price in the US. For a total of $190 (including shipping), you can get 5 pens of Lantus from Canada. That's 1500 units which is enough to last most cats at least 1 year and some cats up to 2 years. (Mark's also will sell an individual pen for $50 plus shipping)---Basaglar, which is also Glargine, is even a little cheaper!
Also, although every pharmacist will tell you that you have to buy new every 28 days, that's nonsense. If kept in the fridge, it will last a good 4-6 months. The only reason they have that 28 days is because when they submitted it for testing, the manufacturer only asked the FDA to test it for 28 days! So officially, that's what they have to say!
ProZinc is another good insulin but it's veterinary only. Chewy has about the best price. A 10ml vial is about $105 which is 400 units of ProZinc.
If your vet writes a script for Lantus or Basaglar and
buying from Canada is still too much for you,
Diabetic Cats In Need is a charity that helps low income caregivers with the costs of treating their diabetic cats so they don't have to be euthanized or rehomed. We can also provide you with a meter, strips and lancets if even the Relion Prime from WalMart is more than you can handle.
Hang in there! You're in the right place! I think if Juicy had ketones when she was at the vet, he would have told you right then so hopefully that's one thing we don't have to worry about.
As for your husband, if Juicy is on Lantus/Basaglar and you buy from Canada, you're looking at about $15/month for insulin, $36 for 200 glucose strips, $2-10 for 100 lancets and $15 for 100 syringes. (approximate). So more like $60'ish per month...nowhere near $250
