no you cannot put turtles and iguanas in the same cage.. separate them.
Yes, you can put your Shih Tzu in a cage provided that the cage is big enough to accommodate it.
Yes you can! In fact it is recommended that you do!
I think it depends on how big the turtles are.
In a big cage
you should not put them together because tortioses live on land with little water. eastern painted turtles love water and spend most of their time in water. what i would do is get two different tanks to put them in. by the way eastern painted turtles are omnivores and hermann's tortoises are herbivores. the two wouldn't work together.
No, they will most likely eat your fish.

A Big Cage
You can but there is a big big chance of them mating and having lots of kids
Most definantly! You could put a thousand in and it would ok! Parakeets are very social. Just make sure you have a big enough cage.......or an aviary!
It is recommended to have only one hamster per cage to prevent territorial disputes and fighting. Hamsters are solitary animals that prefer to live alone, so it is best to provide each hamster with their own space and resources in their cage.
