Thanks, but I meant a source we all could refer to. Perhaps you just misunderstood your vet. Just to clarify, so that the inexperienced here won't be misled:
Water soluble lubricating jelly (of which K-Y is only one brand) is a common substance for lubricating tubes, gloves or instruments of rubber, plastic or metal which may be inserted in, uh, various orifices in the reptile body (as well as those of other life forms, of course
). I like it because of its great slipperiness and because it spreads easily and adheres well initially, but washes away easily. It is non-irritating to mucous membranes.
You can buy little sterile foil packets for pennies apiece if you wish and keep them in your reptile room(s). I usually just have a standard-sized tube which I keep for purposes of probing reptiles for sex determination, or for lubricating the occasional tube for introducing food or medications, the subject which started this thread. If you squeeze out a blob of the stuff for each use instead of inserting instruments inside the tube, it stays plenty clean for our purposes.
Heck, as far as oral use goes, dsreptiel, this product is recommended as a moisturizer for the human mouth during radiation therapy and chemotherapy. You may use it with confidence!
Of course, it should go without saying that whatever lubricant you choose - jelly, oil, or water - for your medication/feeding tube, you are careful not to introduce any of it into your patient's glottis when you insert or remove the tube.
