Erm, how is Evo Points calculated? I'm very confused.. Welcome back, Kisumi! I presume you're thinking of Poochyena in this question?
If a pokemon battles, or does some other mission-critical task (like destroying a generator), it gains an Evo Point. Pokemon only gain one point per mission, no matter how much they do. However, I'm not sure tracking Pachirisu is enough to qualify.
Ginji or Brian, feel free to overturn this decision. But at least Hoothoot gets a point.
Evo points can also be gained through reffed stadium battles or eating Rare Candies.
(P.S. Would your owl consider ALL water types as fish? Even Blastoise, Ludicolo, or Suicune?)
