  2. Improper Digestion: Guinea pigs cannot properly digest the sugar in raisins because they have a sensitive digestive system. The indigestion of this excess sugar can lead to painful cramps, inability to feed, and diarrhea.
  3. Dental Issues: since raisins are sugaryand chewy, they can cause dental issues in guinea pigs. They can stick in the pig’s teeth and easily cause gum disease or tooth decay.
  4. Excess calcium intake: Although calcium is important for your guinea pig’s bone health, if taken in excess, it can cause kidney and bladder stones or urinary tract disease. As guinea pigs grow older, they need less calcium in their diet.
