AHA! Caught You Foxy.

I never get photographic evidence of Foxy annoying Jonty but here it is. Foxy not only stole Jonty's 'baby' but also his chewy hide boney thing and then stood over them to protect them. I think what he's really doing is goading Jonty into chasing him because as soon as Jonty gets close Foxy is away with the baby. If Jonty doesn't chase him he, Foxy, lies down and bites the baby to make it squeak.
In the meantime, Jonty was telling us that there was something underneath the Ottoman that he couldn't reach, you can see his paw scratching at the Ottoman. Turned out to be his blue squeaky ball. I fished it out for him and then Jonty played 'Fetch' with me making it very obvious that he was ignoring Foxy's pleas to play.
