Because your Espurr is a male, it would evolve into Meowstic Male. It has more support moves than attacking moves, so I would suggest a support moveset for it. For the stats, you could put max in HP and Speed.
Here is a sample set:
[email protected] Clay/Leftovers
Ability: Keen Eyes (suggested: Prankster/Infiltrator)
EVs: 252 HP/252 Speed/4 Def or Sp.Def
You can breed Meowstic to get different offspring with a different ability; you might be able to get Infiltrator. This will help you alot. You can find its breeding group here and click the Egg Groups (it is Field).
