A couple of rabbits got in before you installed the electric netting

The netting has been up for around 12 weeks now, I think I would have seen
it as the ground was empty when I put the fence up.

I've never known squirrels to do this. My money is on still on a couple

About as likely as you not noticing a goat in your house for a couple of
months.

Wouldn't be impossible in our house, I must admit ...
