Jackfruit should not be given to cats. Since cats have problems digesting sugar, jackfruit can make them throw up, have diarrhea, and become dehydrated. Better options to give to your feline include strawberries, apples, bananas, blueberries, cantaloupes, and seedless melons. Due to their carnivorous nature, cats do not require the nutrients in fruits like jackfruit. Even while eating exotic fruits occasionally can be healthy, always talk to your vet before giving your cat any.
