Captive skunks have been reported to
adept well to diets of dry commercial dog and fruits and
vegetables.
Only lactating and young growing
animals should be fed ad libitum. In the summer, 2 to 4 ounces/day
of dry ration is adequate for adult animals. Due to their tendency
to become obese in the fall, they should be feed only one to two
ounces of food per day. They should be frequently weighted to
adjust their food intake to prevent obesity. The normal adult
weight is 10 pounds.
Handling
All pet skunks should be anesthetized prior to handling. This
minimizes the likelihood of bites and scratches, and avoids
scrutiny by the Public Health Department. A handler wearing thick
leather gloves can restrain the animal by the nape of the neck for
injections.
Reproduction
Mephitis mephitis are usually monestrous and mate in
February or March. Overt signs of estrus are slight. Her vulva
swells slightly and exhibits a mild mucus discharge. Estrous
females are receptive to males until either pregnancy or
pseudo-pregnancy occurs. At this point they become very aggressive
toward males and females alike. Lactating females are also
aggressive and require individual housing.
Females should be housed in an
all-female facility during pregnancy since the presence of a male
in an adjacent cage may distress a female, resulting in abortion,
stillbirth, or postpartum loss of the litter due to poor mothering.
The pugnacious behavior increases during pregnancy and lasts until
weaning. The gestation period is 62-66 days, with parturition
occurring in mid-May. The litter size ranges from 4 to 10, with a
mean of 4 per litter.
Neonatal Growth and Development
The newborn animals are pink and wrinkled in appearance.
However, the characteristic black and white dermal pigmentation is
present. By 8 days, some animals are able to emit musk when
disturbed. The eyes open within 18-28 days. Associated with open
eyes are several behavior changes including increased aggression,
directed spraying, a marked decrease in vocalizations. By day 32,
they are very likely and capable of directed musk emission when
handled. The teeth erupt by day 34-40 and the young begin to eat
solid food. Weaning is usually completed by 8 weeks in small
litters and 10 weeks in large litters. By 4 to 5 months of age, the
litter mates must be separated. They probably continue to grow
slowly until they reach their adult weight at 10 months of
age.
Descenting
At 6 to 8 weeks of age, the skunks are better able to undergo an
anesthetic episode, and the musk glands are less likely to rupture.
Animals older than 8 weeks have larger glands which are more
difficult to remove. The procedure commences by grasping the neck
of the musk gland near the papilla with a hemostat. Grasping the
papilla directly with a hemostat may result in its removal, making
removal of the gland very difficult. Once the neck of the gland is
grasped, slight steady traction is applied so that the pink muscle
layer can be scraped away from the shiny, white musk gland.
Alternately, a circular incision around the base of the papilla to
free it from its cutaneous connection may be performed. The muscle
tissue is scraped away until the gland is free.
Removal of the anal sac in skunks
under 8 weeks with enlarged glands is accomplished by inserting a
22 gauge needle into the neck of the gland and withdrawing as much
of the yellow fluid as possible with a 6 cc. syringe. Reducing the
size of the gland facilitates its removal.
The surgical site is left open to
drain. No other post operative care is required.
Musk
The principle compound in skunk musk is butyl mercaptan. It is a
sticky liquid that can be projected accurately up to 12 feet.
Clinical signs of being sprayed are temporary blindness, nausea,
convulsions, loss of consciousness and burns of the skin. The
mercaptan can be made soluble, harmless and odorless by strong
oxidizing agents such as the alkaline sodium or potassium salts of
halogens.
Clorox oxidizes the mercaptan to
sulfate or sulfone, removing the odor by breaking sulfur completely
free from the carbon compound, which is odorless. The carbon
compound, sulfate or sulfone, are water soluble and can be readily
removed by washing.
Immunizations
Skunks are susceptible to several viral diseases of carnivores.
These animals should be immunized using a scheme similar to the dog
and cat, commencing at 6 to 8 weeks of age.
