Mine adore basil, you should think about growing it, it does really well in pots. I´ve started doing that as it doesn´t last very long and you can´t refrigerate as it goes an awful brown colour. If you´ve got a garden, you should start a herb garden then you´ve got fresh all the time. You should try other herbs, mine have dill every day as they love it but they also like sage, rosemary, tarragon and parsley. Most bunnies go mad for coriander although mine aren´t that keen on it. A bit at a time to start to see how they go but they are really good for the buns.
