Unless something has changed, I'm fairly certain that feeding a pet doesn't reset the bonding timer. I've have several pets that I've feed, thrown in the stables and a week later taken them out and feed again, and they not bond, so I put them back in and take them out the next day, feed them and have them bond.
What is your taming and lore at (natural and with jewels) and what are you trying to bond. Some pets can be difficult at times. I know a person who once had a pet 3 months before it finally bonded.
