We have given you our thoughts, as well as our reasoning. It is based on our concern for you and Chloe that we feel an emergency vet visit is required. However, the choice is yours. Please continue to test and post results, and keep the SS updated. Many people who come on later may go straight to the SS vs, reading this long thread. I'm not sure who else is on, or will be on, but I need to go to bed. Hopefully you can get her up above 50 soon, but I would still say have the phone number of closest emergency vet handy, since it is hard to know if or when Chloe will have symptoms. We often say it is better to be a day too high than a minute too low. We just want the best for Chloe.
I'll leave you with some suggestions. Try and alternate gravy/honey with food/honey, so this time you gave gravy with honey, test again in 20 Minutes, and give a teaspoon of food with a teaspoon of honey if the numbers still haven't moved. Next test 20 Minutes, teaspoon of gravy with teaspoon of honey. Continue until she is up above 50, then continue to test for two hours from the last intervention of high carb or honey. As I mentioned before, even if she is above 50, do not go to bed. Keep testing, since the numbers can go back down, as honey can wear off quickly.

Good luck.
