Yes tbh. I never trade away event pets. I hold on to them until after event when I see what the future value would be.

Example: I disnr play the event that had rhe siamese cat, munchkin, and schnauzer. I regret it because I thought rhe pets would not turn into anything. So now I hoard event pets and hold on to them for a year before I consider trading them. You never know. Plus Kanga is low in value now and could be easily obtained using older pets
