Both of mine LOVE kale, green peppers, and tomatoes. Lemmy is also a huge fan of cucumber. Charlie likes broccoli and cauliflower, but Lemmy will eat it once everything else is gone lol.
Does anyone else cut the veggies up? I feel like I spoil my boys a little too much lol. I'll rip up the lettuce a bit but everything else I cut into bite-sized pieces. Or if it's something new that they turn their noses up at, I'll use my food chopper to get it nice and small so they can't help but get a piece here or there with other bites (that's how Charlie fell in love with cauliflower hehe). The one time I gave them a cherry tomato without cutting it, they kind of stuck their teeth in it and then pushed it around confusedly.
