Used everyday by the lodger has saved my kitchen walls.
The lodger (who is now a permanent resident as her previous owner no longer wanted her) started to scratch at the walls and the curtains. She used the boxes (from here) but was still having a cheeky scratch when i wasnt around. This is her absolute favourite, she scratches on it everytime she comes in and lays/sleeps on it. She plays with it on her own and i also poke the feather duster type toy through the sides. Which sends her bonkers and she catapults around the house, coming back to scratch, catch it and eat it. She isn't particularly bothered about the balls but that doesnt detract from it, its a fantastic toy. I will definitely continue to replace it and will buy some for xmas as prezzies for the families furries. Firm favourite and excellent value for money.
