WHAT IS KNAWNER 1.0?

It goes to say that dogs and cats can't be friends, nor can cats and birds, birds and worms, and so on. But may you tell me, how animals like a Knawner, and a Meowcow would do to eachother if they were to come into contact, or a Knawner and anything? As of now, a Knawner is a fairly unknown creature. All we know, is that it wants perfection and perfection is what it is. Would this mean a Knawner would only be able to interact with a cat and not destroy it, yet with anything else, a Knawner would destroy anything that is not perfect? Tell me please, I am still scared to dm this creature.
