What would be an animals source of glucose if it only eats meat?

If an animal exclusively eats meat, its source of glucose primarily comes from gluconeogenesis, a metabolic process where the liver converts non-carbohydrate substrates like amino acids and glycerol into glucose. Additionally, certain fatty acids can be converted into glucose through specific pathways, although this is less efficient. In carnivorous animals, the consumption of protein can provide the necessary building blocks for these glucose-producing processes.
