I get mugged for them every moring - even Bramble who runs and hides at tea time until she's seen me go safely back indoors comes running in to get one each morning. I know each morning that they're both eating before I go to work this way and as Bramble's prone to stasis, I figure that outweighs any unhealthy treat damage, although to be honest they're not full of sugars or milk so I think they're pretty good in comparison to other products.
