Waving from the Kawarthas.
Lantus.
You can walk into any pharmacy and buy Lantus. Only humans need a prescription. Just say it is for your cat. Ask for the package of 5 vials – roughly $120. You can use it to the last drop and the package will last you a long time. Chances are the large vial of Lantus will probably expire before you use it up.
Strips.
Alpha Trak strips are crazy expensive. Even human strips are expensive in Canada (but the insulin is much cheaper than in the US). A lot of people use a human meter - FreeStyle Lite. It takes a small drop of blood. Strips are roughly $80 for 100. You will be going through more strips than you think. It is worthwhile saving PC points and using them to buy the strips at Shoppers Drug Mart. If you are a senior or have a senior relative close by, take advantage of their Seniors Days. Some people check Ebay for deals.
There is a human glucometre with very cheap strips. The downside is that it takes a much larger drop of blood and I found it read higher than the FreeStyle Lite. The biggest downside is that the strips are not available to buy at a drug store at a moment's notice or in a crisis. You can only buy them online and would need to have 300-400 in stock (100 in your hypo kit) at any given time. With everything backed-up with the virus, you may not get an order as quick as you would like.

Food.
There is nothing special about the prescription diabetic food except the price. The prescription dry food is high in carbs. In fact, there is no dry food available in Canada that is low carb. Your vet may want to switch you to Purina DM wet food. It is considered low carb but again, pricy. If your vet insists, buy a can or two, then tell the vet that your cat will not eat it.
Fancy Feast and Friskies pates (and
only the pates) are low carb and very easy on the wallet. Do get a couple of cans of Fancy Feat Gravy Lovers (high carb) for your hypo kit. Also, I believe the small cans of PC pates are low carb.
DO NOT SWITCH TO AN ALL WET FOOD DIET UNTIL YOU ARE TESTING REGULARLY. Switching to low carb wet food can make a difference of up to 100 points. It is best to gradually transition to wet food, have your hypo kit handy (just in case) and to test on a regular basis while doing so.

It would help tremendously if you could set up a spreadsheet. If you ask questions or need someone with you during a low numbers situation, the spreadsheet is the first place a person will go.
Hope this helps.
