Have a very long time flirted with the ton and then bought our two 4-pawed monsters for Christmas. The joy was somewhat restrained in our - that's when the two tomcats our daughter very much larger. Meanwhile, it is used by all 16 feet - only our cat (he is very large) is still a bit cautious. The barrel has a good foothold. It also stops when 5kg cat hanging on the side. Outside is a ton completely covered with sisal (I guess). This is used very busy - it can indeed stretch suuuper tuned. Katz 'can make really nice since long. There is a sleeping cave. this was not really used so far. For the lower two levels, as you can through a hole inside prima up and down there. Suitable super as a hiding place for the final assault ... :-) top the ton is softly padded with a big cuddly soft rim which can be pushed even to the outside when Katz 'even need a little more space. I just hope that they will continue to survive the daily attacks and makes all four cats have long joy. Should be able to expect for the money. I would every cat owner who flirts with acquiring such a tonne, recommend this large barrel, because the smaller issues are probably still more for kittens (and these are growing very fast).
