Strictly No Elephants by Lisa Mantchev (2015)
When the local Pet Club won’t admit a boy’s tiny pet elephant, he finds a solution—one that involves all kinds of unusual animals in this sweet and adorable picture book. Today is Pet Club day. There will be cats and dogs and fish, but strictly no elephants are allowed. The Pet Club doesn’t understand that pets come in all shapes and sizes, just like friends. Now it is time for a boy and his tiny pet elephant to show them what it means to be a true friend.
