I wonder when they'll add part 2 of the season.
I may have to rewatch part one, forgot some of what happened due to pain meds...
I've never seen much serious fighting (mostly I've seen boxing, which is more of a dominance thing. it's pretty cute when they do though, they just stand holding hands/shoulders in a boxing position for a few minutes). but I'd see where, when I first tried to introduce Meadow to Pippin. Pip would get very tense, fur standing on edge, and would even hiss

and then would lunge at Meadow. Meadow did that a little to the new ones the first few times I tried to do introductions.
I've heard though, if rats do genuinely fight-fight, there's usually blood, and you need to either distract them from fighting (like putting a blanket over them) or separate them.
also, I was wondering. with your art page, would you accept a request based off of a description if the person doesn't know exactly what to request? (like if they described hair-style/type, color, eye shape/style, outfit-style, ect)
