I agree with this! I thought I might be the only one thinking they were coming too fast because I'm still a pretty new breeder and have a very small budget, but it looks like I'm not!
One special collection per season could be an alternative, with more special kitties throughout the year that we can get by breeding, like the Mardi Gras or St-Patrick's day cats.
I got 2 easter kitties, but I'm still figuring out my Valentines, so I'm not going to unpack them yet... It's a shame I won't get a chance to discover new traits, but I can't handle much more kitty planning or spending
