Can you tell what it is yet?

Jakey had been out most of the day and when he came in around 3.30 pm, he wasn't interested in having anything to eat and went straight to sleep and stayed asleep for most of the evening.

I don't think he's his usual self, so I've decided he's staying in tonight as I think he's eaten something that disagrees with him. It's nothing I've given him, I might add. I know for certain that he has been eating grass, as we have evidence of that, if you know what I mean!

He does seem to catch and eat way too may things whilst he's out on his wanderings and I keep telling him it's not good for him!
