The main symptoms of anxiety in RABBITS are:
Freezing: If you just freeze, it is probably a sign that she is nervous. Often this will be in combination with trying to become as small as possible by pressing their ears against her body.
Big eyes: Big bulging eyes are often a sign that your rabbit is looking at something they feel they should fear.
Aggression: If your rabbit becomes aggressive (i.e when picking it up) this is because their anxiety triggers a fight or flight response. CBD can reduce the anxiety, making your rabbit easier to handle.
Heavy breathing: Similarly to humans, when anxiety is becoming too much, rabbits will start breathing heavily.
Repeated movements: Some bite their nails, others shred items they have in their cage. Rabbits cope with their stress by biting their bottles or bars or by stamping their feet.
