paperback- The cover is a little worn. Writing on inside cover

Socks is one happy cat. He lives the good life with his affectionate owners, Mr. and Mrs. Bricker. Ever since the day they saved him from a life spent in a mailbox drop slot, Socks has been the center of their world. And he always has everything he needs—tasty kitty treats and all the lap room he could want!

But when a new baby arrives, suddenly the Brickers have less and less time for Socks. Little Charles William is the one getting all the attention. Socks feels left out—and to show it, he starts getting into all sorts of trouble! What will it take to make Socks realize just how much the Brickers care about him?
