Don't bathe bunnies it can cause issues and frighten them just clean off their bum or other area with a wet cloth. Just make sure nothing touches their ears 😊
Twiggs is an outdoor bun and he dosent wear a harness , unless I bring him to the front yard cos he likes to run into the neighbors yards! But yes it is a h style. So If he is blocked off from escaping and danger/harm he do sent really need a harness.
