My cat archy, gone now for many years, attained the age of 21--and if you had asked him, his long life was due to eating watermelon, cantaloupe and avocados whenever he could! He once crashed a neighbor's bbq to eat their watermelon.
In his autobiography, Chuck Jones tells of a childhood pet cat who loved cantaloupe so much, the family would give him a whole one, uncut, and he'd push it into a corner, gnaw his way in and eat the whole thing, often ending up wearing the remains like a helmet.
I'm curious, can carnivores actually digest plants? Does the melon actually contribute to the cat's metabolism or does it just pass through and gets excreted unchanged?
