Level 7

Difficulty

 * 35 cats can be a lot since only peashooters can shoot
 * Wall-Nuts can protect you from scratches. But since they come faster, it isn't guarantee that will help you protecting the other plants even if up to 2 can be on screen

Strategy

 * Plant your very required plants first before you can plant a Wall-Nut
 * Don't let the cats scratch your plants
 * Gather more sun to place more Wall-Nuts
