We weren't trying to tell you what to do. Clearly, prescribing practices differ between the UK and the US.
I followed your suggestion and Googled making the transition between insulin and Senvelgo. I was able to see the UK packaging/labeling instructions. The instructions that Larry included above were not included. It appears that what Larry was able to find is geared to consumers.
At least in the US, the warning is much stronger about not using either of the SGLT-2s with cats that have previously been prescribed insulin. In the UK, as long as the vet has provided you with informed consent, it's your decision. You appear to be comfortable with the risks. I would also be curious what insulin you were using with your cat. Insulin choice has been fairly restrictive in the UK until recently. My understanding is that vets were mandated to use Caninsulin. It's only recently that Prozinc was an option. In the US, and much of what we see on this board, Lantus (glargine) is used more often than any other insulin.
At this point, there is still very limited research using either Senvelgo or Bexacat. And, frankly, there's more research on the use of Senvelgo with ponies than there is with cats. We're all learning about this new class of drugs and their use in species other than humans. There are clearly cats that would benefit from having an oral option available. Because these drugs are still so new, we are very careful with making recommendations. There are any number of caregivers who lurk and don't post. That being the case, we do not want to mislead or misinform anyone and we want to make sure that if there are differences between countries, prescribing practices, etc. that those differences are clear.
