EARS Check ears at each grooming. They should be clean and smooth, with no obvious odor or redness. Take care not the put swap in too deep, as it could push wax in deeper, or cause other problems. If ears are scaly, red or sore, your bunny may have mites. A topical mite solution can be used, or in severe cases your vet may prescribe Ivermectin.
Most bunnies learn to love grooming time.
For those that don't, a quiet, gentle, non-forceful, secure approach is the way to go. Eventually your friend will learn to like this time, or at the very least to trust you and allow you to care for her.
