If you are looking at amplified sound, bear in mind that the amplifier will have to run on some sort of power supply, either a 9V battery or perhaps 5V taken from the PET's own internal power supply.

Here's a mono amplifier which includes an integral volume setting control:

For any module like that, you will also need a conventional (low impedance) speaker to connect it to. Maybe you already have one.

You can also buy a mono amplifier kit complete with a speaker, which would be a good project to give you a little bit more experience with soldering:

Note the above kit has a fixed gain (no volume control) so you would have to experiment with resistor values or add a volume control yourself.
