In fact, depriving a baby monkey of a normal relationship with its mother and family group can result in a lifetime of neurotic behavior. Even the smallest squirrel monkey can open a cupboard and spill containers of flour, sugar, and liquid in minutes. Larger monkeys can open refrigerators, turn on faucets, rip through window screens, unlock outside doors, and turn over chairs, tables, stereos and televisions. Toxic substances and medicines must be kept locked. If you can't stand cleaning up urine, feces, and occasional diarrhea, don't get a monkey.
Monkeys are very excitable animals.
They will immediately relieve themselves whenever and wherever they are upset. And monkeys cannot be easily housebroken. Though you may be somewhat successful diapering or toilet- training a young monkey, once the monkey reaches maturity, training is usually forgotten or ignored. Some cities and states prohibit the keeping of some or all primates, while others require special permits. Don't wait until you have a monkey to learn it's against the law in your city or state.
