There are many different techniques to do this....

A Prop-1 and sound card with speakers could control everything.  Have a look at the audio section for some of the different sound card options options.

Pneumatic or electric?  Your choice really.  Sounds like you could do it with a single motor for scratching noise and/or another motor or electromagnet for the kicking action. Motors could be activated using relays connected to the prop-1.  Of course, you could use a pneumatic cylinder to do the kicking action, but then would need a selenoid valve and stored air (compressor or tank.)

Trigger?  Will it run constantly or be triggered by some event?  If triggered by an event, then a PIR or mat switch would work well depending on the environment.
