the concept of mixing up a little meat cocktail dates back to bill haast. most serpentologst have their own mixture. i have been reformulating mine for about 20 years and this is what i have settled on. the meat based baby food is the starting point for most ppl. i added the baby food powder cause it is made for new borns and very easy for the baby to take in, i added the gateraide for the other vits needed, that are not included in the meat bases. also it seems to bring up the energy level in a weak snake. i used it on waters for probably about a year. i have used it to inject froozen toads for my eastern hogs since about 2003.
