when my lop hit 12 weeks, she outright SHUNNED her "birthday" veggie (romaine lettuce) and I was sooooo sad! I pressed the issue the next day and she finally gave it a try, now she loves it! I'll try carrots again at some point, I suppose... right now, neither bunn will eat the actual carrot so that goes to me. Gaz likes the leafy bits of the tops but won't eat the long stems and Nala only likes the stems (it actually works out quite nicely).
they like cilantro but I hate the way it smells... they like turnip greens and romaine lettuce, too. Gaz doesn't like the white/vein part of the lettuce, though - she'll eat the leafier part from around it first and only sometimes goes back to eat the tougher bits.
