We don't add variants for cat units mainly since an unit variant could have different forms and the number are too many.
For example, marshmallow cat could have fall under as two variants units: basic cat on its basic form and basic gross cat on its evolved form.
There is also princess punt unit for example cat princess is basic cat in basic form but becomes evolved gross cat on its evolved form. Chicken cat also and many more.
Unlike enemy units page which each page contains only single unit and a form. The player units page could cause conflicts and confusion due to multiple forms in a page. Perhaps until later when we are start using more minimized layout then we could add variants.
