congrats ! ur suddenly turned into your fursona/dollsona/idealized form/whatever.
what's the worst part? what's the really annoying part you're like "well obv this is the greatest thing but i wish i had realized how annoying X would be"
(this is assuming no one is weird about you suddenly being a dog or whatever; purely "what's the worst Practical part of your impossible idealized form?)
I've seen many responses to this around the general vibe of "fur upkeep hard :(" and I've decided that in my head, if furries are real then their fur require less upkeep than a fursuit to keep clean and soft.
And it is expected for every bathroom with a tub or shower to have one of those thin wall of air dryer things so one can be completely dry in 5 minutes. I can have my bigass tail washed and dried in 15 minutes if I need to.
I am not adding a drop of inconvenience to my fantasies unless it excites me.
