This guide shows the locations of caged cats that are needed for five individual achievements as well as a sixth achievement for getting all five. This sixth achievement ("Tika") does not unlock immediately upon freeing the last cat, but rather at the end of the level IIRC.

Look for a pit that has vines descending into it - there's only one such pit in the level. You can safely fall down and find Tonks.

Daisy is hidden pretty far in the level, just past the moment where you first encounter frogs followed by spiky plants. There's a movable box in front of a stump with some "unusual ground" visible underneath. Drag the box away from the tunnel entrance and drop down.

Again, the hidden kitty is far in the level, kinda near the end. Look for climbable vines above a windowsill, with a trashcan underneath. First, retrieve a movable box just to the right and drag it so you can access the vines. Once on the ledge above the door, jump toward the tree. Keep going in that direction and a secret area appears with Sheldon in it.

This cat is located just after using the crane for the first time, where you jump from one moving platform to another high in the air. Immediately after landing on the construction site, there is a sack of concrete that is (suprisingly) movable. Push it off the edge here.


But do not jump down after it! You will get hurt falling from this height. Use the slide at the other end of the platform to get down safely. You will see that the falling sack dislodged a manhole cover. Jump down and find Abb.

In one of the indoor sections look for a vending machine with a ventilation shaft entrance immediately after it on the ceiling. Jump inside (first using the shelf to get on the vending machine) and rescue Snicker.
