>There is a 2 stage cat Pokemon that is Normal when captured but will inherit the fathers primary type as its 2nd type when hatched and the color/pattern varies by typeSo assuming this cat is in the Field Egg group (
http://bulbapedia.bulbagarden.net/wiki/Field_(Egg_Group)), then the possible types for it will be:
>Normal>Normal/Ground>Normal/Fire>Normal/Fighting>Normal/Water>Normal/Psychic>Normal/Dark>Normal/Ice>Normal/Electric>Normal/Poison>Normal/Grass>Normal/Steel>Normal/Rock (assuming Rockruff is in the Field group, which probably will be)
