The generation that is redefining old age is making growing old easier for its pets.

"Baby boomers are keeping their pets longer and are willing to do $5,000 surgeries on them," says Bob Vetere, president of the American Pet Products Manufacturers Association. The Web site www.seniorpetproducts.com sells products, including dog diapers, and sponsors online discussions on pet topics.

As dogs and cats get older, hip dysplasia and aching joints are common ailments. Now there are solutions to give pets a leg up. The company Petmate makes nonslip carpeted pet steps ($39.99) at the right height for sofas or beds. Solvit's telescoping ramp (about $150) was designed for SUVs and vans, and some customers have used it in bedrooms, too.

To help older pets climb out of the pool, there is Skamper-Ramp ($47 to $85). The lightweight plastic ramp lets dogs and cats find an easy way out.
