Re: Boomer down to 29 he won't eat now so gave syrop directl
yes, that's why you have to wait long enough for the syrup to wear off before assuming he's going to stay up.
as a last resort, you should know that you can administer corn syrup (or honey) rectally using the kind of syringes that are for oral meds (no needle). He's been very persistent in the low numbers today, so always know the vet is an option if you can't keep him up. Lantus hypos can last a long time.
Has he had any symptoms at all of hypoglycemia? any staggering, stumbling, etc.? one list of symptoms is on the Low Numbers sticky. Cats can have low numbers without symptoms, too, although if they get low enough they will.
give your husband kudos for testing when he didn't feel comfortable with it at first. you guys have kept Boomer alive.
