Guinea Pigs have sensitive stomachs. Highly acidic fruits such as limes can cause stomach pain for them. In addition, limes have higher sugar levels than fruits similar to it.

Unfortunately, Guinea Pigs’ digestive tract of cavies is not suitable for breaking and digesting the amount of sugar that limes have which contributes to the risk of stomach cramps, tummy aches, and indigestion.

Low energy level, shortness of breath,  and inactivity caused by obesity can deteriorate Guinea Pigs’ health and lifestyle which can shorten their life expectancy and promote diseases that can be fatal for them.
