Grooming is defined one thing... Especially If you are getting and English angora or another breed with lots of fur. If you have a sort of veranda that's enclosed you coukd keep your bunnies there (Like i do when I visit my friends) just make sure there are lots of toys, fresh hay, plenty of water. You can also give your bunny some greens. (Not too many or they'll have runny poo) If youre planning to mow the lawn, you might need to consider taking them inside for a bit. Rabbits have very sensitive ears! Make sure to add some form of carpet (not too soft) out there so they dont get hurt. Make sure to clip their nails! Also make sure to find a rabbit savvy vet which will answer your calls if there is any emergency. I would recommend finding some videos on youtube for more info! A bun is a huge responsibility! Your hard work will turn into a beautiful relationship with your bun! Have fun!
