Small pets o.OFollow

Im new to WoW and Hunter.. I heard something about being able to get small pets in this game, not hunters pets but like a cat for example.. I heard something on the official site that small pets can have an effect on your regular pet, is this true? and if so, what type of effect does it have?

you can get small pets but they range from 40 silver to 50 gold or more depending on the pet. Humans=house cat night elves=owls
undead=roaches tauren=prarie dogs gnomes/dwarves=mechanical squirrals And i have no idea what the trolls and orcs get.

Mechanical squirrels are actually not bought they are crafted with engineering.

Anyone can get any type of pet be it alliance or horde pet. Pets are bind when used so i could buy the cockroach(horde pet from undercity) and put it up in neutral AH. Then an alliance character can purchase it from the neutral AH. Some pets are dropped off mobs such as the dragon whelplings and some are crafted such as the mechanical chicken/squirrel. Others are even neutral pets purchased from neutral vendors such as the grey chicken in shimmering flats.(cant remember its name)

Yeah i forgot to mention the collectors edition pets....the monster thing is called a zergling i think.
