I disagree. I think it's because of supply and demand and perception.
There are fewer Catcoins on the market and currently a strong demand thanks to Catcoins riding the hype wave of Dogecoin. The perception is that they are valuable since there are less of them.
And maybe thats what the dev had in mind when he created the coin. Create fewer coins, ride the doge wave, then pump 'n dump. Still a scam.

Would it be wrong to point out no premine on cat? Perhaps that's why its been picked up so rapidly, what has the creator got to gain from this over and above any other miner?
Early miners on cat have made some nice profits.
