How do you calm a hormonal rabbit?

Often times bunnies that are in the adolescence stage, between 4 to 8 months tend to get nervous, agitated, or aggressive with their owners. Below are some of the various ways you can use to calm a hormonal rabbit.

Whatever the case, it’s advisable to wait a few minutes until your pet is less agitated or nervous before engaging. To calm it down, try petting the top of its head specifically at the ear base. Alternatively, you could also offer your bunny their favorite treat or chew toy to ease their nerves.

As a precautionary measure, wear pet grooming protective gloves prior to interaction with your bunnies especially if you’re yet to earn their trust. This will most likely prevent you from being bitten or scratched.

How long do rabbit hormones last?

On the other hand, uncastrated or unspayed bunny’s hormones tend to last longer.

Male rabbits should be neutered as soon as their testicles descend, normally around 2 to 3 months. On the other hand, you should spay Does as soon as they’re sexually active, around 4 months old.


How do you know if a rabbit is unhappy?


A rabbit that’s unhappy tends to be lethargic and mostly in a hunchback position. They may also go into hiding for long periods even when they’re energetic.
