Oh hun, don’t worry! i haven’t found an official “pet bowl” for Xerxes (my dog) or Mustachio (my bunny) so i technically eat out of a pet dish every day.
Heck my cat eats my food all the time. I have wasted so much food throwing it away because Ziva (the cat) jumped on the couch and ate out of my plate that I was running out of food! So now I just stand there and wait for her to scoot over and we share! I don’t really care to be honest. She doesn’t always eat all of it and they are my family. I know most people think it’s gross but it’s not a big deal to me.
If it is for you, look at it this way the dish had been washed, it sounds like, so it was clean! There’s not really anything for you to worry about, germ wise. And also, a dish is a dish. As long as it’s clean it doesn’t matter who used it last!
The way I see it is that it’s no different then eating out of your own bowl or, for me, eating after my fiance or sisters. Ziva is part of my family. And I hope it’s the same way for you. If it bothers you see if the bunnies will eat of your bowl. Then y’all are even!
