Thanks for asking NF - I asked my next door neighbor, who's her vet. She said as long as she's eating and pooping fine, then I shouldn't worry. Luckily it was a small plum so I think she'll be okay. I always use a bag to pick her pooh out of respect for the neighbors, so I'll still keep looking for a couple more days. When she was younger, I found little beads, tiny elastics in her poop - that's her only downfall, is eating things she's not supposed to. Most of the time if we see her with something, she'll listen to the command 'drop it' - but sometimes we don't see her.
