Why are you suggesting this if you are not sure if the snake is strong or smart enough to break through? I promise you the snake is BOTH strong and smart enough...
This is an all time bad idea.
Like others have mentioned a Rubbermaid container is probably the best plan, but when you have an animal who needs care, it is your responsibility to take care of the problem NOW, not next week. The OP needs to pull whatever strings necessary to make it happen.
