Hi Samantha,
That's great that you're starting to get the hang of home testing! As you get better at it, you will notice the spots less. We thought our poor Eddie's ears looked kind of beat up early on as well, but after just a few weeks, and us getting better at testing, you usually can't tell where we've tested. If you're seeing little red splotches, that's where blood has leaked a tiny bit. You can help this by applying firm pressure to the poke with a cotton ball or piece of gauze to stem the bleeding. You can also use neosporin pain relief (not the cream kind), which will help the pokes heal a bit faster, and help with pain if Hidey's ears are a little tender. Are you using a lancing device? Is the poke going through the ear? We started with the longest setting and are now down to the second shortest setting on our device.
Are the readings you posted from your pre-shots? Have you been able to get any tests mid-cycle, like between 5-7 hours after the shot? It's a lot easier to see if insulin is doing it's job properly if you know how low his BG is going when it's hit its peak effectiveness. I encourage you to pop over to the PZI area of the board and check out a few "condos" so you can see how a cycle looks. Generally, it's going to produce a smile shape - sometimes it's a steeper "smile" and sometimes it's a shallower "smile." A cat's pre-shot numbers can be high even if the dose is too much, rather than too little. This is called bouncing. If the insulin is causing their BG to drop sharply or into lower numbers than they are used to, their liver can release glucagon and other chemicals as a protective measure, which results in a spike in BG. For example, you can see pretty regular bounces on Eddie's spreadsheet at pre-shot time. He's a bouncy boy and many of the cats here are. Every cat is different in how they respond to lower BG numbers, but bouncing is pretty common. Sometimes the best way to deal with bouncing is to actually reduce the dose. If Hidey is staying in those high numbers all day, however, that might mean that his dose needs to be increased.
We had this very issue when we first started insulin. We were bringing Eddie into the vet up to twice a week because each time we got a read at the vet's it was going higher and higher, up into the low 500's even (on a human meter, which would be even higher on the Alphatrak). His dose kept increasing due to the high numbers we were seeing at the office visits. We started home testing a few days after we began administering 3u bid of ProZinc. The night after our first successful test, we realized that Eddie was dropping almost 300 points, and his high numbers at the vet's office were because he was dropping too low at mid-cycle, so his body was fighting back and causing his BG to skyrocket back up by the time of his pre-shot test. We didn't realize this at the time, but we were bringing him to the vet at the time of day when his BG would naturally be its highest anyway, so the vet tests weren't giving us a good idea of what the insulin was actually doing. About three and a half weeks later, we are now at less than half of that dose and are seeing numbers that are just as good if not better than when Eddie was on 3u.
If you haven't already, I also encourage you to set up a spreadsheet like the one you see in my signature for Eddie, so you can more easily see trends and patterns. Other members also look at a cat's spreadsheet when giving dosing advise. If you hop on over to the ProZinc area, you can also get specific advise regarding that type of insulin, since each type has it's own separate protocol. Sue in the ProZinc is incredibly helpful, and there are several other members that are more than willing to jump in and help.
Looking forward to seeing you post Hidey's "condos" in the PZI area!
