Kittify accomplishes exactly what its name promises. Here's the Kittehsburg Address:

Four score and seven years ago our fathers brought furth on this continent, a new nation, conceived in Lipurrty, and dedicated to the purroposition that all men are created equal.

Now we are engaged in a great as catnip civil war, testing whethepurr that nation, or any nation so conceived and so dedicated, can long endure. We are met on a great as catnip battle-field of that war. We have come to dedicate a purrtion of that field, as a final resting pawlace fur those who here gave their lives that that nation might live. It is altogethepurr fitting and purropepurr that we should do this.

But, in a largepurr sense, we can not dedicate -- we can not consecrate -- we can not hallow -- this ground. The purrave men, living and dead, who struggled here, have consecrated it, far above our poor pawepurr to add or detract. The world will little note, nor long remembepurr what we meow here, but it can nefur furget what they did here. It is fur us the living, rather, to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rathepurr fur us to be here dedicated to the great as catnip task remaining befure us -- that furrom these honored dead we take increased devotion to that cause fur which they gave the last furll measure of devotion -- that we here highly resolve that these dead shall not have died in vain -- that this nation, undepurr God, shall have a new birth of furreedom -- and that gofurnment of the cats, by the cats, fur the cats, shall not purrish furrom the earth.
