About Us!

Welcome to our page! We do our best to provide to-be and current bunny owners up-to-date info on the best care for their house rabbits. When we adopted our first bunny in 2005, there was almost nothing on the internet to tell us how to care for him. Just in the past few years, information has exploded online, and now it can be confusing! We try to simplify it by posting weekly articles on current issues, daily care, concerns, proper feeding, and other info so you can enjoy your house-bun! If you are just finding us, feel free to look through the older posts also. Please email us if you have any questions! Happy bunnies make happy hearts!

Not Good....Trancing / Hypnotising rabbits (Tonic immobility)

Tonic immobility (TI) is a state of motor inhibition that can occur in prey animals as a last defense against a predator.  The rabbit will lie motionless, thereby giving the impression of being already dead and encouraging the predator to release its grip, giving the rabbit a last chance to escape.  This state of temporary hypnosis can be induced in domestic rabbits by laying the rabbit on its back (dorsal recumbency) and flexing the head against the neck; as long as the head remains flexed the rabbit remains in the same position.

Rabbits in dorsal recumbency show a drop in blood pressure, heart rate and respiratory rate along with a depression of spinal reflexes and the abolition of the righting reflex.  There is also a reduced response to noise and painful stimuli.  According to a study by Danneman et al, 1988, tonic immobility cannot be induced in approximately 25% of rabbits.

TI is commonly referred to as "trancing" or hypnotizing rabbits and in the past has been commonly used by vets and rabbit owners as an easy way of examining a rabbit or clipping its nails.  It was previously thought to relax the rabbit but this has been discredited in recent years, with studies (in particular, a 2007 study by McBride et al) showing increased heart rate and respiration following an episode of TI .  In addition, after TI a rabbit's behavior may be adversely affected in that it hides away more, grooms itself more and shows less inclination to explore.  The more often it is done and the longer the rabbit is "tranced" for, the worse the effects.

Although trancing is still a debated subject, with many rabbit owners advocating it as a useful tool, it is commonly accepted that TI should be avoided where possible as it is detrimental to the rabbit's health.    In the UK most rabbit experts, welfare organizations and vets caution against the use of TI or recommend it is only used as a last resort; for example, when a vet is examining a very nervous rabbit and other means of restraint have failed.

If the bunny flops himself over on his side or back, that is totally different, and has not shown to cause issues. No need to run up to Bunny yelling! He is just happy and comfortable. 

If nail trimming for you and your bunny is an issue, try this common technique. Typically this will work, especially if the bunny has some greens to munch on during the trimming!
