indestructible toys?

Thanks for all the suggestions.  We've tried the FatCat toys and Kaila demolished all those and then Shiner got the skins.  The tire on a rope he destroyed both rope and tire and he actually has a second tire that he doesn't really play with anymore.  He's not a kong fan either.  Stuffed toys get gutted pretty quickly around here.  Forget tennis balls and he ate a racquetball that had survived both Cinder and Kaila.  He's a pretty efficient demolition machine but he's cute, so I think I'll keep him.     

I would try the tire biter line by mammoth pet. They are made of real tire material so they are wicked tough. They have tires, sticks, balls, etc. http://www.mammothpet.com/tirebiter.asp You will find a lot of knock off tire toys but they are not made of real tires so they are not really indestructable - make sure you get a mammoth pet one.

There are also toys made from real fire hoses that are super tough. They are by a company called Kygen http://kyjen.com/dogtoys/?page=dt-firehoses

Another one I have heard is really durable is the Galileo bone by nylabone http://www.nylabone.com/dog_chews/
