Cat Trees and bedding
You can spend hundreds of dollars on cat trees especially if you shop at Petsmart or Petco. Yes, cats need to have something they can work their nails on to save your furniture from being their favorite thing to claw and snag. I use sheets on my couches not just because my dogs shed but to keep the kittens from having claw accidents until they understand that the Cat Tree is the only place to work out. So sheets do help but a Cat Tree is a must have. The absolute best place I have found is on Amazon and Groupon for cat tree deals. As the Sisal rope wears out you can buy extra at the hardware store and just hot glue or power staple gun it on. *Asthma suffers need to get a tree with NO carpeting*
My Favorite Cat Tree brands in order. They can all be bought on Amazon.
New Cat Condo's- For the money it is my #1 pick **It is built with real wood. These are the most durable I have ever had.
Go Pet Club- Ok but made with cardboard.
