"Monkey"

I don't think that monkeys are good pets. First of all, they are ugly. They also make loud and annoying sounds. A human being would not be able to supply all of the needs of a monkey. Monkeys are somewhat fast and like to climb things. That's a bad combination for something that is going to be living in the house. Monkeys are going to be going around the house, breaking a lot of things trying to climb it. They could also start a fire in the house, if they knock down a lamp or a conventional  heater. Monkeys are hazardous and should not be a pet.
