2x Bambu Refills

Swapping in a fresh insert takes about five seconds, and my cat was back to scratching immediately instead of losing interest. The two-pack is handy since I can keep a spare on the shelf for when the first one gets shredded.

The cardboard is dense enough that my cat actually prefers it over the other scratching pads around the house. Swapping in a fresh one took about ten seconds and the fit is perfectly snug.

My cat wore down the original insert in about three weeks of daily scratching, and these replacements fit the frame perfectly without any wobble. The cardboard feels just as sturdy as what came with the unit, so I'm glad I grabbed the two-pack for the inevitable next swap.
