This enemy attacks and walks quite fast. His attack power is strong compared to other enemies introduced early on, so be careful when dealing with him the first few times. Later on, however, a squad of regular cats should be able to hold him off until the Cat Cannon or some other high-power cat finishes him off. Another simple way of dealing with Jackie Peng would be to use fast-attacking cats and defensive cats, for example, Giraffe Cats coupled with Wall Cats.
Strategy
This enemy is rather difficult due to its fast attack speed and quite high damage. Evolving Cat to Macho Cat is a good idea, but don't expect to beat 2 Jackie Pengs so easily. Using cats like Bird Cat can help a lot, but it must be protected by Cat/Macho Cat and Tank Cat/Wall Cat. Either way, if you have trouble in Dubai even with various guides, just upgrade your attackers until you manage to kill one of the Jackie Pengs die, as once one is dead, the other one has no chance of surviving.
Use it's single target attacks to your advantage and block him out with a steady line of Macho Cats and Wall Cats, while using Gross Cat to deal fair damage to him. If you're unable to stall him, try gaining Treasures to activate Energy Drink and upgrade Tank Cat and Research.
Later on, Jackie Peng becomes a nuisance at best, so no real strategy is needed.
