I do agree that Isabelle is likely an adult. But let us bring up points as to why it still looks very concerning when porn of said character is consumed as something one likes.
-This game has childlike proportions beccause it is a game most likely made for all ages. It is meant to be cutesy and from what I can tell, Isabelle is a naive little dog that just wants everyone to be happy (I barely know the character, sorry. I am going by what is said of her.). She is meant to be a family friendly and by extension, child friendly character, so of course she is adorable and bumbly. She is meant to appeal. But not in a sexual way.
- Eevee is a 30 something year old adult, with the world wide internet of furries drawing porn of anthro animals at his hand. He could easily be attracted to adult furry characters or characters that are not made by an industry that tries to appeal to family friendly values.
-Eevee has a fiancee. He could fap to the ugly cat beast that he calls "girlfriend" or whatever, like a halfway normal person. Unless of course, PK is no longer in the picture because she was getting too old for Eevees fetish.
-Eevee regularly "defends" porn of underage or underage looking characters because "they are fantasy!!!1!", says that "cp is just pixels on a screen!! Nothing to be jailed over!" and has an supposedly underage fursona that is regularly involved in sexual acts, whilst dressing like a nine-year old.
eevee would probably think he's way better and prepared than the therapist and leave in a hearbeat.
