Welcome Karen and Mr. Peepers!

We all understand the overwhelming feeling but feline diabetes is treatable! It's not a death sentence and we have ways to help it not break the bank either

. Can't say anything about the insulin price they gave you because not sure which one it is for, except I've never heard $200 every 2 months. My first vial lasted me 3 and I still have it with some left as a backup. I have not heard of generic brand insulins for cats but either way, have to wait to confirm which insulin

.
Food - The expensive prescription diets are 100% unnecessary and actually a lot are too high in carbs for diabetic cats. Most here feed Friskies pate (non-indoor formulas) and Fancy Feast pates (Think they're called classics). Since you have not started insulin yet, you should make the food change before hand. You'll definitely want to home test, for some reason a lot of Vet's say it's not needed. Well, ask if they would give their human baby / toddler insulin without checking BG first

. Home testing has saved many a kitty's life here.
This next section I post looks overwhelming so I'll try to keep it short!

Signature information is super helpful for a quick glance of kitty history and helps those of us with bad memories:

For home testing if your Vet is OK with it, they will probably push the pet meter, AlphaTrak 2. Many of us use a human glucometer, ReliOn Confirm/Micro (Walmart brand) is very popular due to test strip affordability. That's where the cost can be an issue. AlphaTrak 2 strips are bout $1 per strip. ReliOn C/M are about $0.36 per strip. Apologies if I've overwhelmed you more, I like to put things in one place for you initially, and I tried to answer some questions

. Feel free to ask ANY questions here! This is a support group for Mr. Peepers and YOU!
