This is probably a dumb question ... but I have to ask.

Is it not possible to housetrain a monkey?

You said the new monkey you are getting wears diapers? Is that because it can't be housebroken, or does it have a medical problem of some sort?

I have just always assumed, knowing nothing about monkeys, that they were housetrained like a dog or a cat? I have always heard monkeys are very intelligent, so I assumed they would easily housetrain.

Not true?

Just curious.
