First off some pretty bad news, Yaoyorozu and Kadokawa have been in negotiations since Oct but Yaoyorozu have apprantly pulled out after Kadokawa refused to give up control of KF. So the odds of Tatsuki working on S2 are lower than before. That being said, a petition is going around.

Sand Cat's VA had some things to say:
1st tweet:
Frankly speaking, after I decided to perform KemoFure's ED and I was shown the synopsis, the game was shut down and I thought, "Is this anime going to be alright?" However, as a newbie, I couldn't voice any complains, and I gave it my best trying to imagine what the anime will look like and continued composing. After seeing the general response to the first episode, I thought with resignation that it was really going to flop (I'm sorry for being too honest).
2nd tweet:
However, with each episode more and more people started to talk about it. Even I started to enjoy watching and wondering what would happen next episode, and at some point these 30 minutes started to feel really short. The ones who allowed this anime to grow bigger and bigger were, no doubt, Director Tatsuki, the voice actors, and finally, the whole staff.
3rd tweet:
I want to express my immense gratitude to everyone who contributed to creating this enormous thing that was the first season of Kemono Friends.
I don't know what will happen now, but I hope everyone will be able to keep laughing with Friends. Director Tatsuki, you did a really good job. I can only express my gratitude.

There's also this guy who said they spent the last few months trying to work out a deal but Kadokawa refused to budge and it fell through.

But there's some good news for Tatsuki. He got to attend C93 as general public for the first time in 10 years and got a trophy hashtag thing from twitter in which he thanks his supporters.

His station attendant animation was also lengthened, so at least he's been working on something since he was fired.
