Multiple Choice and sub choices

I am looking for a contact form that will allow me to create multiple menu drop down such as contact form 7 but with another sub option depending on what has originaly been selected.

So for example:

Multiple Selections

• Cat
• Dog
• Cow
• Rabbit

If Cat is selected then another drop down would appear with perhaps

• Food
• Water
• Milk
• Play

Anybody know if there is such a plugin that can do this?
