The American Red Cross has had one in the past, but interest hasn't been sufficient to hold one lately at the Racine site, Kate Adkinson-Connor wrote in an e-mail. She's the educational services manager for this region.

She wrote that the Red Cross "will happily supply the materials, instructor and certification cards for a per-person fee for businesses/community centers who are interested in either training their employees or hosting a training at their facility."

If you're willing to trot up the road a little, the Wisconsin Humane Society offers a CPR and first aid class for owners of cats and dogs. The next one is Jan. 7, from 6:30 to 8:30 p.m. at the facility, 4500 W. Wisconsin Ave. in Milwaukee.

The cost is $60, and advance registration is required. To sign up, call Nora Hart at (414) 431-6156 or go to the society's Web site at http://www.wihumane.org (click on the "WHS Calendar" tab, then find the date).

Why was the flag at the Downtown post office at half-staff the weekend of Oct. 24?

Most likely it was lowered to honor Spc. Kevin Graham, a former Kenosha County resident who was killed in September while serving in the Army in Afghanistan, U.S. Postal Service spokeswoman Marge Oehlke said.

Post offices follow governors' proclamations to determine when to lower the flags, and Gov. Jim Doyle ordered them flown at half-staff Oct. 25. A memorial service for Graham was held that day in Union Grove.

What is the difference, if any, between "skim milk" and "fat-free milk"?

The difference is that "fat-free" takes up more room on the label.

The terms are interchangeable, said Jane Losee, regional program manager for the Wisconsin Dairy Council. They mean the white stuff in that jug contains less than 0.5 percent milk fat.

For the past month, my neighbors and I have seen a lot of holes in our yards about the size of half-dollars. What are they from?

They could've been the work of skunks digging for grubs, said Marty Johnson, wildlife biologist at the Wisconsin Department of Natural Resources' office in Sturtevant. Garden stores sell grub control products, but those need to be applied in summer, said Patti Nagai, a horticulture educator for the UW Extension in Racine County.

Pepe LePew does have an alibi, though, because skunks "don't make any neat little holes," she said. They leave shallow, irregular marks because the grubs are just below the surface eating grass roots, Nagai said.

So, if these holes are deep and uniform, she was comfortable in saying they're from chipmunks.
