Constipation in a cat can be the first visible symptom of a more serious condition such as a tumor, so it is very important that you have your vet examine your cat. Any period of prolonged constipation can also be very dangerous for a cat. However, if your cat is simply defecating less often, there are dietary solutions. Cooked vegetables such as beans and pumpkin will provide added digestive fiber, or if your cat won’t eat such food you can attain fiber supplements such as Benefiber®. Always seek veterinary advice before using such supplements.
