The Humane Society of Southern Arizona is offering free vaccinations for the first 50 cats and dogs brought to a mobile pet clinic set up at a south-side grocery store Thursday evening.

The clinic will be in the parking lot of Food City, 428 W. Valencia Road, from 4 to 5 p.m. Thursday.

Cats and dogs will be be given vaccinations for distemper, upper respiratory infections and rabies and will be de-wormed. Dogs will also be given a vaccine for parvo.

Bordetella and feline leukemia vaccinations will be available for $10.

The free vaccinations are funded by a grant from the American Society for the Prevention of Cruelty to Animals.

“The vaccinations are important not only to protect the animals from diseases but also to protect the general public from disease such as rabies,” said Teresa Truelsen, a human society spokeswoman.

The humane society offers three regular vaccination clinics each week. The clinics happen Wednesdays from 6 to 7 p.m., Fridays from 12:30 to 1:30 p.m. and Saturdays from 7 to 8 a.m. at the Companions for Life Center, 3465 E. Kleindale Road.

Rabies shots cost $13 and a combo vaccination for distemper, parvo and upper respiratory infections costs $10 at the regular clinics.
