I think that these have just changed from Very Common --> Common
I love to trade and I will look at any reasonable trades. My ultimate ambition is to collect every pet on CS so I will trade for anything on my wish list. I don't often collect items so if I have anything that you want then please feel free to include them in a trade.
I am always happy to do same litter swaps for anything without a rarity even if I don't need the pet. Just send a trade.
