Cat owners in Saskatoon are being warned to watch out for a deadly feline disease.

According to the local SPCA, the city has been hit by an outbreak of a disease called Panleukopenia.

On Monday, the SPCA announced it is under quarantine after two cats with the disease were admitted in October. There have been at least two other cases, according to Patricia Cameron, the executive director of the Saskatoon SPCA.

The local pet shelter is urging owners to vaccinate their cats as soon as possible, because the disease is so contagious.

"The vaccines are very effective, and the best possible way to protect your pet," Cameron said in a release.

According to Cameron, indoor cats are also susceptible to the disease.

"When you take a stroll, go from your car to the house, or do yard work, the virus can come into your house on your clothes and shoes," she said. The virus can survive for up to a year in certain environments.



However, if owners believe their pets have the disease, they should be brought into a vet as soon as possible.

Symptoms of Panleukopenia include depression, lethargy, loss of appetite, fever, vomiting, and self-biting on the tail, lower back, and legs.

The disease attacks the lining of the digestive system and can lead to bloody diarrhea, rapid dehydration, and pain. Panleukopenia can also leave cats vulnerable to other diseases because it compromises their immune system.
