Some of my guinea pigs are fussy about their food, and it can be difficult to get them to eat other brands of emergency nutrition foods like this when they are ill or not eating well on their own. I usually feed them some each month as a 'treat' to get them used to eating from a syringe so if/when they get sick, it's easier. I thought I'd have a hard time transitioning some of them to this but I needn't have feared - they all tried to steal the spoon and run away with it! They absolutely loved the flavor. I am glad to have found another food option for nutritional support when my guinea pigs are ill. Also, although I fed them a small amount as I introduced a new food, none of them got sick/bloated/anything else - it seemed gentle on their tummies. Very happy to have found this product and highly recommend it! It's also a very fine grind, so it works well in syringe feeding.
