Are we going to see more developments in the catpin universe?
Yes. I realize sometimes it takes us several weeks between stories due to life’s commitments. This time, I took a break from the catpin universe and posted an unrelated story about two moms wrestling in a backyard called, “Wating At The Door” (Wrestling board). But I am back again, getting into catpin trouble. I know Kelli is cooking up new stories as well. Thanks for reading! 
Am I the only person who is hoping for a continuation of the catpin stories?
There are many of Kelli and Kiva's fans out here who are waiting for new installments of their excellent respective series. But real life sometimes causes some of our favorite authors to devote time elsewhere and not to the stories on this board. We have been spoiled by the quantity and quality of these series, that it feels a little empty without them. Things have gotten a little slow lately, with several authors not being able to post anything in a while. Anyway, I expect they will be back sometime in the future, just not right away..
I know that I am still working on several new stories and I'm pretty sure that kiva has some new stuff in the works.
For those of you who don't know, I usually work on several stories at once and when one "takes off", I go full speed with it. Right now, I have a couple competing still. As of now, you've got the opportunity for another fight at the Valkyrie's Palace, the Jolene rematch, a random catpin encounter (that may end up having the first "couple's match", the MvsM part taking place in the MvsM series), and the introduction of new, previously introduced part of the catpin world that has several returning characters.
I also have a couple of side projects (a pro style series with several FFJ characters playing roles, the Rivals series with Charlotte... plus it's summer, we have a new puppy, etc... lol
