Re: Moderate ketone reading Bubba starting insulin today hel
Deep breath. You may not have seen this scenario but many of us have. You're doing all of the right things.
Humulin N, like others said, is a faster acting insulin than Lantus. It's also more potent but shorter in duration. Lantus is gentler but longer acting. Right now, there should be 1 goal: get rid of the ketones. FWIW, trace levels can be managed at home. There are 3 key things for you to pay attention to.
Fluids: Subcutaneous fluids are how this is usually treated, especially if the cat is at home. An IV drip may be used if the cat is hospitalized. You aren't equipped to put your cat on an IV. It's a positive sign that the vet found only trace levels and sent Bubba home. You can ask your vet to show you how to administer sub-q fluids. We have videos of how to do this. Adding as much water to his food as Bubba will tolerate will also help.
Infection/Inflammation: You noted on your spreadsheet that the vet gave Bubba clindamycin. Please talk to your vet about this. Was there actually a URI? Is Bubba's temp back to normal? Was a blood panel run to see if an infection was present? You also noted Bubba's gums were inflammed. You may want to ask your vet to re-check this. It may also be contributing to the problem. Now may not be the time to consider a dental but you may need to think about it sooner rather than later.
Food: Getting food into Bubba is essential. Ketones develop because a cat is metabolizing fat, not protein. Fats breakdown into fatty acids. The more fat is being metabolized, the more these fatty acids build up and they throw the body's pH (acid-base balance) off. If not dealt with, not only do ketones develop, the risk for DKA increases. By making sure Bubba is eating, protein will be metabolized and the cycle doesn't occur.
You may want to order a blood ketone meter so you can keep an eye on Bubba's levels and so you don't have to keep stalking him to the litter box.
NovaMax makes a good meter. Just be aware that the strips for any ketone meter are expensive. Blood ketones meters tell you exactly where the ketone levels are at the moment you're testing. Urinary ketone levels are hours old and aren't as precise.
