The only place I've found Hip Action is actually a doggie bakery. I checked Petsmart and the bigger places, but no one carries it... even though the Hip Action website says they are supposed to have it. It's made by Zuke's and you can get in on their website, too.

My vet gave me glucosamine/chondroitin tablets that she swore cats loved. Yeah, right. They were superexpensive and my cat wouldn't go anywhere near them. The Hip Action is a fish-flavored treat. My boy is so into them that when he hears me open the bag, he'll start clawing at my hands if I can't get them out fast enough!

My boy is a couple months shy of 10. This winter he has taken a liking to the big heat grate in the dining room floor at night instead of with me. He seems a little less likely to climb the stairs, maybe going up and down 4 times a day instead of 12. He still comes up stairs for my morning nap (I work an odd schedule, and the cats have to wake me up to feed them in the mornings, I read a bit, then back to bed), to sleep either on my legs or under the covers on my chest. When we get out the laser pointer or remote control car to play with the cats, he won't jump up on the furniture, but still zips back and forth from room to room as fast as he can. He still climbs up the big homemade cat tree at least once a day (5 feet straight up of sisal rope wrapped around 6 in. pvc pipe, then another foot of burlap around a 2x4). I'm not certain that 100% of his heat-seeking behavior is due to age - as he is part Siamese, spent the first 7 years of his life in Arizona then moved to Minnesota.

The girl cat is 6. When the two of them are napping together, she often wraps herself around him, and maintains the alert, like she is letting him get rest while she keeps watch. This is a role reversal, as he raised her, and often guarded for her when she was younger. She climbs the big cat tree several times a day. Climbing is really her thing, though. Not only will she climb up, but she can also turn around and climb down.
