I was sent this great photo from Tracy. She says it's a 1905 postcard she found at an antiques store where she lives. As you can see it's a cat dressed up and sitting in a highchair with a caption that reads "What's Delaying My Dinner?"
I guess the cats of 1905 (like the people of 1905) spoke in a more refined manner.

1905: "What's Delaying My Dinner?"
2008: "I Can Has Cheezburger?"
I believe that you have found the worlds first ever lolcat!
seriously though, with a history this old maybe there is a anthropological or sociological study in the works?
My dinerz -- whar iz it?
Or:
WHARZ MAH FUD?
Still, the fact that kittens were valued for more than just controlling mice, even back then, is so nice. I'm going to be saying "aww" all day long whenever I think of this photo.
Internetz, 2009 - Children with no knowledge of lolcats have been dressing up cats for hundreds of years and many adults have laughed at the resulting feline predicaments. The more recent addition of bettah spelln haz decreased social and age barriers to nil.

i'd prefer to work from a higher-resolution image if you have one; the result would be much better.

Will be glad to do this to full size scan if made available.
Great find!
