Is it safe for a cat to eat birch bark?

While birch bark is not toxic to cats, it is not recommended as a food source. Cats may chew on it out of curiOSity, but consuming it could lead to gastrointestinal issues or blockages. It's best to provide your cat with a balanced diet specifically designed for their nutritional needs and to monitor their behavior with non-food items. If you suspect your cat has ingested a large amount of birch bark, consult a veterinarian.
