A Parvo outbreak has hit the Grand Valley killing dozens of cats and dogs.

It's been a problem for some time and seems to only be getting worse. If you own a dog or cat make sure they're vaccinated against this deadly virus. There have been dozens of Panleukopenia, feline distemper, reports in Mesa County and Roice-Hurst Humane Society says they've seen Parvo infected dogs all summer long.

The mild winters are mostly to blame. The warmer weather along with the extra warm summer extended the kitten season, creating more cats, and cases of Parvo. The problem has stressed the system. "It's resulting in more sick animals being brought to us, more animals that we either are seeing don't make it or at the point where they have to be euthanized because there is no rehabilitation or treatment for them,” says Anna Stout, Executive Director for Roice-Hurst Humane Society.

If you're not sure if your pet is protected it's only about $20 to get them vaccinated. Contact your local vet and get them fixed up. If your dog or cat comes down with the illness it will cost you much more to have them treated. Of even worse case, they could die from the infection.
