If it’s possible to do a combination of the mentioned options, that would be great.
I think the best option would be to power up Catnet and have him trail the kittens. I can trail the kittens with a small upvote as well, and if enough of us trail the kittens, we can achieve a high enough vote value that the bunny can finish it off effortlessly.
My reasoning behind that is that 350 Steem Power doesn't really pack much of a punch vote-wise. You'd need about 3000 SP for each kitten in order for them to cross the dust threshold on their own with no help from the bunny.
