Indoor run?

[carrotflavour]

OK so I'm making a new indoor run for guineas I'm getting on saturday. I was thinking the basic grid material for the outside...and for the base I remember reading about bathmats, so I might try and look for some of those.

I live in the UK and plan on going to B&Q and have a look around.

Does anyone know if b&q does any grid type of material? I dont mind having to saw it to shape it as long as it isnt impossible to saw/cut. And what about the base- does anyone know if they do Coroplast?

The last run was a basic board flooring (it had a coat on it so could easily clean) and a rim of wood around the side. But it was an awkward shape and hard to move around. Also my piggys used to jump out of it (piggys are smarter then you think, teehee) and play free range...

The cage we have is barely big enough (if I'd found this site first I would have made them one, believe me) so I plan on giving them hours and hours of run time.

Thanks.
