This Saturday is a really big day for Haven Humane Society. For one thing, it’ll be the 10th annual “Petfest”, with lots of activities for people and their pets from Noon to 5PM at the shelter on Eastside Road off Highway 273 just south of Redding. There will be more than 30 vendors, several interesting canine demonstrations, and Cinco De Mayo food served by Hartline’s West Mex. Also on Saturday, the carpet cleaner maker Bissell sponsors an “Empty The Shelters” event, during which the company pays all the adoption fees for every single animal that goes out the door. The generous donation by the Bissell Pet Foundation will only be done on Saturday. People who want to take advantage of the offer should go into Haven Humane in the next few days to get the paperwork done ahead of time. The only fee required will be for the city license.
