Even if your rabbit is a single pet and one has no intention
of allowing it to breed, there are important health reasons for getting it
spayed or neutered.
Female rabbits, called does, are in heat 75 percent of the
time. Unspayed females can become quite aggressive; growling, charging, and
biting at their owner in an attempt to defend their cage or territory. Other
hormonal behaviors can include urine spraying and nesting due to false
pregnancy. Spayed females typically do not display these behaviors.
An unspayed female rabbit has a high chance of developing
several forms of lethal cancers. These tumors can develop in rabbits as early as
four years of age or younger. They include cancer of the uterus, ovaries,
cervix, and mammary glands and are nearly always fatal. Other reproductive
problems that might occur include: pyometra (an infection of the uterus),
endometrial hyperplasia, (which produces bleeding from the uterus) and mammary
gland hyperplasia. Spaying a rabbit at an early age, preferably before six
months, dramatically reduces or even negates the chances of that rabbit
developing these life threatening conditions. Female rabbits spayed at an early
age have a potential life span of eight to nine years. This life expectancy is
double that of an unspayed female rabbit.
Male rabbits that have not been castrated may also possess
some intolerable behavioral patterns. These behaviors can include aggression and
urine spraying. Early neutering can eliminate these behaviors. Neutering also
reduces the pungent odor of male rabbit urine.
Male rabbits do not appear to be as predisposed to
reproductive tract cancers as are female rabbits. Nevertheless, neutering can
reduce any chance of testicular cancer or testicular injuries to nil. The
scrotal skin is quite thin and rather pendulous, which predisposes the testicles
to injury. These injuries can lead to life threatening infections.
As demonstrated above, the reasons for spaying or neutering a
pet rabbit go far beyond simple population control; they can lead to a longer,
healthier life for the pet bunny.
