Hi, I'd be interested in your take on this - I know freecycle groups vary on whether they allow pets to be offered on the boards - ours has up til now, but following some concerns, has set up a group vote.
We got a guinea pig off freecycle. a few weeks later she had babies, so we had lots . Luckily we like baby guinea pigs, and I was a bit sorry that our local freecycle banned pets. We got rid of a goldfish through freecycle, when we inherited one in a pond in a house we bought. so really, we found it useful for getting rid of or getting new pets.
