I tried to grow some of the seeds from my hay:

I wondered what it was and if my piggies can eat it?

While I have your gardening expertise close to hand, what is this too?

It was growing in a tray of fushias I bought from B & Q.

The first one looks like a tomato seedling, so not for guinea pigs to eat!
Not sure about the second one but it could be a bramble?
