the cecil poop concern,
are you saying that her end poops are looking like cecils (a.k.a. wet and squishy as if she is edgeing on diarrhea)
or are you saying she is getting more cecil poops.
if it is the second thing, don't worry, thats a good thing and let her have her veggies if you still wish to give them to her.
If it is the first and you still want to give her veggies, then workthem into the diet slowly (give her an added couple more pieces dailyeach week). She needs time to adjust to the new food, butwill thank you for it.
As for drinking more, if you have a bottle to drink from, I wouldencourage a bowl instead (heavy crock so they can't flip it) because abunny isn't made to drink from a bottle and many will only drink asmuch as they HAVE to because of how hard it is to get a good drink fromit. The reduction of water intake the bottle can cause maycause certain ailments dealing in hydration. Use a bowl ifyou can, add a drop of vanilla to it if you need to encourage her more.
As for a salt lick, the introduction of high salt into a bunnieselectory diet won't be harmful as long as your bunny is completelyhealthy. The kidneys are made to filter out extra salt andwee it away (remember the magic words "if she is fullyhealthy"). I let my rabbits have a lick for something to do,but if I start seeing pee or health problems I will take itaway. The increased salt intake will make her drink more, butif she has a bottle and gives up trying to drink before she can getenough, then you are doing more harm then good because she will becomemore dehydrated with the lick then without (its the whole, don't drinkocean water because it will dehydrate you more thing again).
