Along with everything else stated, most of the time these animals end up in roadside zoos or somewhere else due to the handler not being able to care for them. The animals require too much care and especially when they get older.

I do not think that exotic animals should be kept as pets. They belong in their natural habitat. These animals do not adjust very well, when being kept in confinement. Also keeping these animal puts their handler at risk for diseases passed by the animals.

"Replace: Replacing, where possible, experiments using animals with alternative techniques such as cell culture, computer modelling or human volunteers instead of animals.

Reduce: Reducing the number of animals used, by improving experimental techniques and sharing information with other researchers so that the same experiments aren’t being done by many people.

Refine: Refining the way the animals are cared for to help minimize any stress or pain, by using less invasive techniques where possible and improving medical care and living conditions."

I agree with this website, because you could replace animals and use human volunteers or computer simulations. If you didn't want to replace animals, then you could reduce the amount of animal use.
