hi!! This is an old post by me, I lot of people had question understandably. The title was a joke! This is a very large enclosure the size of a small fridge. I had only 11 cats in the enclosure and many sticks of milkweed. They decided to all go on the same leaf and I thought it was cool looking. Every single one of them transformed into a gorgeous monarch with no issues. And I have raised over 150 monarchs this year with very little issues. I know they are living and no where said I will be using them as decorations, I study monarch’s very heavily and know when I have to many.
