I have 2 quakers that spend time with me. I usually wait to feed them after I put them back in the cage. I have had 2 poop free days on my shoulder this week. If Titus starts to back up and scrunch down, this means its potty time. Hold him over a paper or his cage. I have done this consistently, and mine are semi-potty trained. Quakers are very smart and will catch on to anything that is reinforced enough. Good luck.
