I think that he is afraid that some predator may attack him by transforming itself as well. I mean, he will still be in heat.
true. I guess it would depend how bad the heat is. But I'm guessing not all predators are going to go for a mouse. Foxes do since it's their primary prey. but I'm guessing a bear for example wouldn't be trying to eat mice. Well it was just a hypothesis of mine either way.
i wonder if they can change by will in the first place tho? or if it's something that happens with exhaustion or extreme emotions ( like being unable to control predatory instincts?) and if it's possible during a heat?
that's actually a good question. Maybe they change into their animal forms unconsciously just like you said. But he did change into his mouse form there at the end even though he was in heat so at least that we know of I guess
Just a thought but... couldn't the mouse guy technically get away... by turning into a mouse and hiding in a tiny hole? You know like how Jerry from Tom and Jerry hides in his little hole in the wall? Plus.... no one would be able to fuck him in that form.... unless they as well are a tiny species like a mouse.... So it would be impossible since a mouse is tinier than a dick.... In other words, when in doubt, turn into a mouse.... Right?
