Yeah, no... 4 is plenty, thank you.

  I have one cat that has ripped apart two computer chairs, I try not to let her do this again, I think she has learned not to get caught on the chair.

No, I was talking about the solar panels behind the cat   

I think the cat is a long hair tabby, I had to post the video because it reminds me of Mutley, he was my gorgeous tom cat. I still have ripped apart furniture in the house that he lovingly prepared for me.
