Personally I think that's exciting

We used to have hedgehogs in our garden when we lived in our village. We always took care of them with food and water and made sure their housing was up to scratch.

I used to grow pumpkins and those hedgehogs would easily keep those pesky slugs away. Consider yourselves lucky to have them in your garden.

I know just what you mean about the noise. Sometimes it can be much much louder than you'd ever imagine from such small animals.
First time I heard it I wondered what on earth it was and crept out into the garden armed to the teeth

As Michael mentions now is the time to look for any babies. We only ever caught sight of babies in our garden in 2 summers as I remember. You need to be quite lucky to catch them as they don't stay with mum for very long tending to leave home at a very early age which I think is why we didn't manage more than twice to see those little-ones.
