1. They will eat a mixture of meat, chopped fruits and veggies, yogurt, and live insects each day.
2. Usually 3-4 feet tall and at least 2 feet by 2 feet square is the minimum. Bigger is always better, and a large aviary is best. They should have branches, toys, a solid exercise wheel, a sleeping pouch or nesting box, food and water.
3. If they aren't cleaned daily, they smell. Males have a pungent odor whether the cage is kept clean or not. They will urine mark inside and outside of their cage and their urine has a strong odor.
4. No. They will nestle into a pouch against your body but most are NOT cuddly or affectionate and do not crave attention from you. You will be seen largely as a launchpad to jump onto and off of. Many are biters, even if handled regularly from an early age. Bites can be severe enough to require stitches, their teeth can peel bark from trees in the wild.
5. No. They are native to tropical areas and do not hibernate. It is very important to keep them at an appropriate temperature.
Other tidbits: Very noisy at night, jumping, crabbing, and generally making a nuisance of themselves. Will not want to interact with you during daylight hours, they will be asleep and cranky when woken. Must keep more than one. They are social and need the company of their own kind.
Make sure you have an exotics vet nearby before you get a pair or more. They have unique and unusual health needs, and most normal vets are unwilling to treat them. Even if they will treat them, they don't have the experience with the species necessary to do it properly and your pet will suffer for it. Their vet care will also be extremely expensive.
They live on average about 15 years in captivity, so think very very carefully before bringing one home. Most people abandon, rehome, or surrender to a shelter within a year. They are not suitable pets for your average home, and most people are not happy with them once they experience them as pets.
