Ok, here's the problem

At first I named my familiar Gridiron, because it looks like an american football
So, just like it says in the help box, I typed "/pet Gridiron, follow"
And even though there was a yulbar right in front of me which I had just summoned with /pet summon, and I moused over it and it was named "Gridiron", I got the message you see at the top of the chat box. "You do not have a pet named 'Gridiron'"
Guessing it might be because the pet needs two names, I renamed it to "Kickme Imafootball"
Then I typed "/pet Kickme Imafootball, follow" and I got the grey message right below the name change message. Annoyed, I tried putting an underscore between the words and it says I do not have a pet named "Kickme_Imafootball"
Trying some other vartiations, the third of which was just typing in the pet's first name, Kickme, yeilded no better results
So, how do I get my pet to do something other then sit there looking like a lump of poo?
