Animals must be free but safe , therefore, we should limit zoos to one per city. They need to free every once in a while 

When we go to the zoo we see that they are sad ,they are always hungry every time I go to the zoo I never see them get fed,even when is animals which eat plants like giraffes or other animals there is not enough plants for them. 

They must only take  babies to take well care of them ,full grown animals in the zoo must be prohibited.

It is good to have zoos but not to much ,full grown animals know how to take care of themselves it should be illegal to have full grown animals ,babies its okay to have them in zoos ,to take well care of them ,but  we need to keep their family together.

Animals need to be safe from other dangerous species.

Animals should be fed every single one of them every hour, animals which eat plants need more nature .Animals must be protected from other dangerous animals that could hurt them,spray spray stuff for parasites and more dangerous bugs for animals.All babies should be kept with their mom and dad.But full grown babies should be released with their parent.
