Cheers, that's good to know. He's definately improving, and his diet is better than it has been. I have to admit I had been religiously treating for infection because of the problems we were dealing with already but have been a little lax this week (partly due to the improvement and partly because a few big things have meant I've just not been able to be here constantly and so a friend has been doing him for me on those occasions, who was already getting him in, checking him, syringing his medicine (

) and everything around whatever her work shifts were, her own horses and everything else...there's only so much I could expect her to do!), so this may not have helped.
Thanks, will get back on top of that side of things and see how things go.
