My bunny is terrified of her brush! I couldn’t brush her since I got her three weeks ago. It’s fine if I touch her or untangle her fur with my hand but as soon as she sees the brush she look like she’s having a stroke, she starts shaking and running as fast as she can. I gave her the brush so she can smell it and bite it to know that it won’t do anything to her, as soon as she smells it she gets scared and runs away. What should I do?I can’t not brush her!
