3. Cats lack glucokinase, a liver enzyme different mammals use to course of glucose for power, that means they might wrestle to metabolize it.

Nevertheless, analysis exhibits that this isn’t the case. A number of research present that cats can digest carbohydrates as successfully as most different mammals – they only do it a bit in a different way.

Whereas cats could lack a number of the enzymes different species use to digest and metabolize carbohydrates, they upregulate different enzymes to compensate.
