Plush Cat Tree with Two Tunnels. For cats, a scratching post is very important to groom their nails and mark territory. The compact EBI Budapest is made of soft grey plush and has a robust scratching post wrapped with strong sisal. The comfortable basket on top can be used as a viewing or resting place. The scratching post features two tunnels with multiple openings. This makes the Budapest the ideal place for your cat to both rest and play!
