I don't think it's a good idea for a mother to be this active, it's even unrealistic in yu standars. She should start thinking more about the kids instead of moving around unnecessarily, like going to the frigging park.
I swear some new mothers this days...
Anon should also pay more attention, I know he hadn't taken care of yukkuris but it's common sense to not let a pregnant pet to do too much activity.
In many abuse stories, yukkuri who become stalk pregnant without permission are often thrown out into the street. Often the stories begin with the mother and the koyukkuri living in a box. If an abandoned mother in an abuse story can successfully bring her babies to term, I'm sure a pet yukkuri walking in the park under supervision will be fine.
Call me worrywart but I tend to see Stalk Pregnancy as a extra dangerous form of pregnancy for yukkuris.
Kinda why I think it's better to be extra careful, you shouldn't overstimate the strenght of the bulbs and the stalk.
I rather have anon make her do some basic excercise in home than in the park, you mentioned abuse stories on which the pets are thrown and nothing falls, well I had seen ones on which a simple smack on the parent makes the babies fly away.
But this isn't an abuse story, so I rather not use logic from abuse stories, instead I rather use common sense, a stalk and bulbs aren't a very protective form of pregnancy so it's better to be extra careful and reduce the excercise input to the necessary and indoors, doesn't help that we are talking about yukkuris which just makes the needs of being careful even more important.
-EDIT-
Now I realized Zidana was making that metaphor to Random's comment, not to mine, so I apologize for the confusion.
Well in many nature stories it's pointed out the best action is for the mother to not move much and remain comfortable and stationary, specially during stalk pregnancy.
While some lil excercise in home and not too far away of the nest is fine, it is troublesome to picture a stalk pregnant yukkuri bouncing around in a park with all the movement it would take.
Well its difficult since we are talking about a fictional creature, but based on the relative difficulty in separating unripe tomatoes, oranges, tangerines, and other fruit from their stalk/vine/branch I don't feel this is unrealistic.
Note, that I am using a longer pregnancy period then most other stories depict, about a month long. This is relatively early in the pregnancy.
It doesn't necessarily have to be exercising vigorously. Yukkuris don't really exert too much energy as is, especially pets. Yukkuris bouncing about as their normal way of moving, and if bouncing around would mean all the kids fall off.... well, that's kinda silly.
Another thing: I think there's a difference between pet and yukkuris in nature: pets are well protected by humans. In nature, if a pregnant mother got caught by something, she's pretty much dead so its to her benefit to not move too much or to expose herself. Pets has no such fears except from random abusers.
But beyond that, it's really to the author to determine how resilient the yukkuri is. And we all know yukkuris can be pretty fucking indestructible in all the abuse stories... so why not in family friendly stories?
Whatever, I'll agree to disagree, I don't think my suspension of disbelief will be recovered no matter what we say, and since this is FF the point is moot either way, I still think they should be more careful and less carefree about it.
