Move over Dogecoin, there's a new contender in town.[...] At the time of writing one Catoincoin is over 200 times more valuable than a single Dogecoin, being valued at 0.001049 BTC per coin, compared to 0.00000058 BTC per Dogecoin. (Source:

200? Those values add up to one Catcoin being worth as much as 1800 Dogecoins.
Also, the Dogecoin comparison is good as an opener, but I would take out the comparison towards the end:
Just a week since launch and this new digital currency has gained the same attention as Dogecoin once did
This was already stated exactly that way as an opening statement and you've already expressed that we're taking it one level further than doge. The rest of the last paragraph is really strong, I like it.
Catcoin more closely resembles Bitcoin in terms of its overall mining difficulty and circulation
It's actually the same as far as I know, maybe we should emphasize on that?
Just a few thoughts, overall I like it so far though

Also the glaring fact that DOGE is a poor investment. With 50 BTC a day of coins being dumped by miners it's not going to let the price rise for at least 6 weeks at block
halving. Even after halving it's still 25 BTC a day dumped. DOGE has not gone up in a week or more. Only down.
With 160-260 BTC of volume per day for CAT so far... where will people get their coins? Not from miners. They will have to buy them
from sellers. Where are the sellers? They are shrinking in supply as price rises.
