 The study found that cats supplemented with HAMSP had higher levels of propionic acid in their feces, suggesting that this type of starch may be better at providing an alternative source of energy for cats. Additionally, the study also found that these cats had lower levels of ammonia in their feces, which suggests that they may have been able to spare some of their amino acids for protein synthesis instead of being used for gluconeogenesis.
