Common conditions of pet hedgehogs include internal and external parasites, ringworm, cancer, pneumonia, gastrointestinal disease, and obesity. Signs of illness or disease are often vague and non-specific, such as lack of appetite and lethargy.
Weight loss, loose or reduced stools and reduced or bloody urine also can indicate your hedgehog is under the weather. Other signs of a sick hedgehog include lethargy, panting or labored breathing, a dull expression, discharge from the nose or eyes, sneezing, coughing and paralysis.
Many hedgehog illnesses and diseases are caused by environmental factors (such as pathogens and diet), or are inherited (through poor genes). Weighing and recording your hedgehog's weight weekly helps you recognize any changes that may signal an illness. Information Disclaimer: We are not exotic pet veterinarians.
Summary. In common with most wild mammals, hedgehogs carry a range of parasites and are susceptible to a number of dieseases of significance to human and livestock health. Perhaps the most significant diseases known in hedgehogs are tuberculosis, foot-and-mouth disease and rabies.
However if you find a hedgehog staggering around, lying still (not in a nest), with flies around it or obviously sick or injured be it day or night, it needs urgent help. Sick, injured and orphaned hedgehogs are very susceptible to hypothermia.
Hedgehogs can carry Salmonella germs in their droppings even if they look healthy and clean. These germs can easily spread to their bodies, habitats, and anything in the area where they live.
You can provide some fresh water and meaty cat or dog food, but don't try to feed the hedgehog directly.
Hibernation; more than half of all hedgehogs die during hibernation due to cold, fire, flood or someone wrecking their nest.
Dr. Keller says, “With appropriate care and keeping, your hedgehog will live about five years, and some even live longer than eight years.” If you have any questions about hedgehogs, contact your local veterinarian.
Many hedgehogs are busy and want to try to explore but a stressed hedgehog will be much more persistent and not easily distracted. The stressed hedgehog may also twitch or shake its head nervously. It is almost as if the hedgehog is saying “Sensory overload. I can't take it anymore.”
A hedgehog's go-to vocal is huffing and puffing, but he's not trying to blow the house down. This sniffing is a normal vocalization he makes while going about his business of exploring. An unhappy hedgehog, on the other hand, will show his disdain with a hiss or a clicking sound.
Signs of hedgehogs in danger of being too cold are decreased activity, decreased appetite, sneezing (as opposed to puffling). So, if she's not on her wheel and exploring at night, eating her food and turning down mealworms and other treats, check the temperature in her enclosure!
Respiratory infection is often caused by a hedgehog's home being too cold. Symptoms can be loss of appetite, lethargy and heavy or noisy breathing.
Threats: The biggest threat to hedgehogs is probably habitat loss, with the change from pastoral farming to arable crops, over the last 30 years. The use of chemicals in gardens and for intensive farming kills the creatures hedgehogs need for food and may also poison them directly. Many are also killed on roads.
Long-term elevated stress levels, as in humans, can have serious physiological consequences for hedgehogs. The higher level of stress shows that being handled and placed in captivity can cause long-term stress in the animals. This highlights the importance of periods of captivity being as short as possible.
A Quick Guide to Hedgehog Noises:
Grunting and snuffling, like a pig = hedgehog out and about, looking for food. Chuffing like a steam train = mating season. Chirping like a baby bird = hungry hoglets in the nest. Screaming Hedgehog = in pain and distress.
If your hedgehog is acting sluggish, lethargic, uncoordinated or they are wobbly with the inability to move limbs; it may be a hibernation attempt. Some hedgehog owners fear the worst – Wobbly Hedgehog Syndrome – which is a definite death sentence. Between the two, you can determine hedgehog hibernation quite easily.
HEATSTROKE AND DEHYDRATION
If they are laying on their sides then it is very serious. Often seen in the summer months but also dehydration can be a problem in the winter months. Giving a hedgehog dried food, or any food when they are suffering from this condition can worsen the situation.
Speak softly and be gentle with him. Avoid surprising a hedgehog, approach him slowly and quietly. It is best to pick him up gently with two cupped hands from underneath where his fur is soft. They sometimes roll into a ball when picked up, but if you hold him and are patient, he will unroll and sniff around.
Insects are a favorite for hedgehogs. You can offer live bugs, which will also give your tiny buddy the chance to 'hunt' his dinner. Frozen ones are fine as well. Mealworms, wax worms, silk worms and crickets are all good options.
Give your hedgehog plenty to do with an igloo or hideout, exercise wheel, bells, and balls. Adding these items to their habitat will make them happy and keep them occupied day and night. Exercise and rest are crucial for a hedgehog, so make sure there are toys and places to sleep.
One manifestation of salmonellosis in hedgehogs is abscessation of the lymph nodes. The signs of salmonellosis therefore vary, and are non-specific, but can include persistent weight loss, dehydration, loss of appetite, weakness, diarrhoea (often green, mucoid or blood-stained) and breathing difficulties.
However, you should try to use gloves when handling a hedgehog for your own health and safety. Hedgehogs can bite you, but very rarely will that happen. This usually happens when they are young and think your fingers are going to feed them (if they have been fed via a syringe as they had no mother).
Respiratory Diseases of Hedgehogs
Predisposing factors for upper and lower respiratory tract infection in hedgehogs are suboptimal environmental temperature; aromatic, dusty, or unsanitary bedding; concurrent disease causing immunocompromise; and aspiration of material from an oral infection.
