Super, thanks for the info! The site is still up so I guess they are still doing business. I know I don't have to question the strength of the hammocks if they had no problem handling Floppy at 23. lbs (she must be a big all around cat, because she doesn't look fat to me even at her heaviest) I'm sure 8 lb. Claire will be just fine!
Claire -- this is where I got the hammock -- http://www.valeene.com/cat_hammock.htm -- but I'm not sure they're still in business. Please not Floppy being featured on the page, when he was 23 pounds! Also, Daisy and Ivan are on there too.
