Yes it is indeed true. Even I lost some good amount in that bubble. But now the things are getting stable again. One thing I can suggest you is to decrease the price of your kitties so that they can sell. These days cheapest kitties are selling at 0.004 ETH. So you might want to put the prices in that range. For the duck kitty you can put the range of 0.05 ETH -0.005 ETH.
