The Trixie strain finally offers the right length for my rather large cat (British Shorthair), so that they can be stretched with delight. Unfortunately, most of the original tribes of scratching posts and climbing towers are indeed fall quite short of what the advertising photos only once not noticeable at the little cats so. The 70 cm strains resolve this issue. The strain comes fortunately with a complete set bolts and washers, as the thread a different pitch than had my original tribes. Thus, the exchange was not a problem. Difficult could be only in constructions where the screws are not pushed through, but are firmly anchored in the particleboard. From the scratch resistance is also available after a few weeks no problems, the rope is stretched tight enough for the needs me.
