Cryosurgery is now at KAH...small lumps, bumps, tumors and warts removed without general anesthesia, incision or stitches call for more information.


A new and deadly strain of Calicivirus has been reported in a humane shelter in Springfield  Missouri.

If you board your cat or if he/she is exposed to large groups of cats KAH recommends bring them in for the new strain of Calicvirus vaccine.  Two doses are required 3 weeks apart

Hemorrhagic Calicivirus

 Virulent hemorrhagic feline calicivirus (FCV), first reported in 2000, is a feline calicivirus variant that causes severe systemic disease with up to 60% mortality in affected populations of cats. Clinical signs include upper respiratory disease (oculo-nasal discharge, oral ulcers), pneumonia, peripheral edema and skin sloughing (especially on the face and limbs) due to cutaneous vasculitis, and systemic vasculitis with DIC (Disseminated Intravascular Coagulation) that causes multiple organ/system failure which may lead to death. Cell culture experiments with the virulent strains shows that they spread through tissue cultures much faster than the classic FCV strains and are able to infect many more tissue types than classic FCV strains.

Virulent hemorrhagic feline calicivirus has occurred almost exclusively in populations of group housed cats. In each documented outbreak, the disease appears to have appeared spontaneously in the population, most likely by mutation from caliciviruses already circulating in the group of cats. This is supported by genomic analysis of the virulent strains - they are unique, rather than clonal, and have no common mutations that could easily explain the change in virulence. Outbreaks of hemorrhagic calicivirus have been isolated and are very rare. Shelter and rescue catteries are the most commonly affected populations. Several epizootics in veterinary facilities have occurred because of the introduction of a sick shelter cat into the veterinary hospital. Because this calicivirus variant is so pathogenic, the disease usually burns itself out in the affected population over several weeks and general spread to and among household pets in the surrounding community has not been reported. However, in at least one case, veterinary personnel handling cats in an affected population have carried the disease to their own pets at home.

Virulent hemorrhagic feline calicivirus is a very rare disease that most often affects group housed cats. Typically, the disease emerges as an apparent epizootic of upper respiratory disease that causes severe respiratory symptomatology but progresses to produce cutaneous and systemic complications with a higher than expected mortality rate among affected cats. The incubation period for hemorrhagic calicivirus is 1-5 days. Older cats often have more severe disease than younger cats with this unusual calicivirus variant. Keep in mind that this is a very rare variant of feline calicivirus and that the vast majority of cats with clinical signs of upper respiratory disease will have infection caused by the much more common feline upper respiratory disease agents.

Like other caliciviruses, hemorrhagic calicivirus is present in the secretions and excretions of affected cats. Once the disease appears, spread may occur by direct contact among cats, transfer by anyone handling cats, and via fomites. If an outbreak of hemorrhagic calicivirus is suspected, strict quarantine and isolation of affected cats, and scrupulous cleaning procedures must be initiated to contain the infection and avoid spread of the disease.

 No new cats should be introduced into the environment unless testing does not identify the presence of hemorrhagic calicivirus or until the disease has run its course in the affected population. Recovered cats may shed infectious virus for several weeks to months post-infection so they should not be commingled with susceptible cats during this time.
