Not if they are in your bank.
After you obtain a pet -catching it, buying it, etc- you just have to right click the pet in your inventory and click "drop." The pet will follow you but beware of how hungry it is. When it reaches 100 it will run away. Certain pets like cats also need extra interaction or else they will run away. For more information on pets see: http://runescape.wikia.com/wiki/Pets
No. If you teleport away, a pet - or other follower - will follow you. Some followers, however - basically those that are invoked with pouches - will disappear after a certain amount of time - unless you use a new pouch to "refresh" them.
