Describe the bug
Using Easy NPC's and Flash's NPC's. Both have the option for cat npc but yours does not adopt the servers custom resource pack texture for the cat mod. Comes out in stripes? bits? Not sure how to explain.

Expected behavior
For cat npc to adopt server skin without issues.

Is the issue happening in combination with other mods? (If yes, please provide a full list)
Better Cats resource pack. https://www.curseforge.com/minecraft/texture-packs/better-cats-minecraft/download/4784566
Additional context
Could be me being blind or having missed a config setting. If so my apologies but could not find anything related to it.

Thanks for the report. The problem in this case is that it applies the textures from the resource pack, but the needed 3d model is not applied.
Each Easy NPC has it own entity type like easy_npc:cat and not minecraft:cat to avoid issues with other mods and make it easier to difference them from normal cats.
For this reason the resource pack 3d cat model is not applied, which only replaces minecraft:cat, but not easy_npc:cat.

Ah, that makes sense. Thank you for your super fast reply, is there anyway I could make it work together after all? I would love to use your npc's for the cats to make them wander and follow people around.
