Does anyone use Carpet squares as flooring?

You know, those hard squares of carpet that places like Homebase sell? Often used in kitchens and offices?
Do buns like them? do they dig and chew?

Thinking of using a spare one i have so they have something nice to sit on in the bottom layer of their hutch (they associate the newspaper with their litter tray and poop everywhere!! and the bare floor stops them a bit).

Or is it better just to buy a Vetbed oval mat?
Thanks

Funnily enough my boyfriend bought some home from work for me yesterday! He thought they would be ideal for the buns too. Ive laid some out for the boarders and they have been laying on them and none have been chewed so far but I will keep an eye on them and if they start to chew i will remove them as these ones have a rubber backing and are pretty chunky. I don't want any blockages occuring.

I had some of those little flat weave mats for 80p if that's what you mean - only Benny chewed his so he had to lie on the metal dog crate base :roll:

It's these sort of things - carpet tiles.
I'll give them a try tonight as well then and keep an eye on them They are quite heavy and stiff though so more difficult to dig up and chew I'm hoping!

Mine all have mats that have bound edges (£1 each for a 3ft x 18 ")
and none of them have dug or chewed them

They're brill! Bertie digs away at them and they last for ever. I ask shops that sell them for a sample to take home and they usually give me one or two.
