Live and learn? I really hate moments like those ;_; Perhaps E-3000 would be the better alternative? Or even shoe-goo? I use shoe-goo for attaching latex pawpads to the bottom of my footpaws, and it holds so remarkably well, and after a day or so of curing, no fumes remained. I've never tried this for handpaws before though, as all my handpaw pawpads are stuffed fleece/vinyl.

This cost me a few weeks. It's part of a larger assembly.

Yikes :(

Also, it's seeped into fabric that can touch skin. The shoe goo would not be good to work on gloves, but fine for feet.

if you're gonna use an alpha cyanoacrillic adhesive, i'd go with something like zap a gap. many caveats as you seem to have discovered the hard way though. less is more for one thing.
for another, which is probably already obvious, solvents eat foam, and a lot of other things. and of course, yes they'll migrate every place you don't want them, and then remain there wet and lurking, until something, anything, usually the least desirable anything, presses against them, removing their exposure to air, resulting in, well the obvious.

the reason i mention zap a gap, is that it is slower acting then the more liquid and cheaper forms of a.c.c. adhesives, which gives more of a chance to undo oopses, if only by a few seconds.
what makes it useful is that it can make excelent bonds between imperfect surfaces. er but, why an acc adhiesive anywhere near foam or fur? these should be locked away from each other on opposite sides of a vault door, or at least i'd be paranoid not to.

of course i have almost zero experience with anything to do with fursuiting, (other then a crappy head and tail i made back in the day when it was more of a hobby then the cottage industry it seems to have become) but plenty with the use of acc adhesives, and a little tiny bit with various foams and syth-fur.
