OK, so they now have nano sized pen needles, and further still, nano sized with 5 POINT BEVELS for no sting and easy flow out of insulin. Apparently, no tenting is required and, for people, you just point down and inject. QUESTION: For our kitties, is the aim to inject into the fat layer, or just under the skin? For cats, if you are on single unit doses, no half units, as my cats are both on 3 units and 1 unit, why not use the pen needles for ease of care? I've been using syringes, but I need to stream line as I now have a third chronically ill cat (IBD), who also has chronic renal failure, as well as one of my diabetic kitties also has chronic renal failure, so I am overwhelmed here. I note that most FDMB advice is to syringe from the pen, but why not use the pen needles if it makes it easier to administer? Is there a danger I am unaware of? Many thanks for your thoughts.....
