Step 1:
The backside of this paper is completely white. Turn the paper.

Step 6:
Prefold over these 2 lines.

Step 5:
The width of the model is 1/3 of the original paper in step 1. Prefold the model over these 2 lines.

Step 2:
Prefold over this line.

Step 4:
The 2 pieces next to each yellow line are of equal width. Make a valley-fold over this line.

Step 3:
Make a valley-fold over this line.

Step 10:
Make an inside reverse fold over these 3 lines (=mountain-fold over the very short line in the middle and a valley-fold over the 2 longer lines)  Make the same folds on the edge indicated by the arrow.

Step 8:
The places indicated by the 2 arrows are on the same place as the 2 arrows in step 7. Prefold over these 2 lines.

Step 9:
Make an inside reverse fold over the 3 pink lines (=mountain-fold over the short line in the middle and valley-fold over the 2 longer lines). The edge indicated by the small arrow below is folded to the folding line indicated by the upper smaller arrow. Make the same folds as above at the place indicated by the large arrow.

Step 7:
The places indicated by the 2 arrows are one the same place as the ends of the folding lines in step 6. Prefold over these 2 lines.

Step 16:
Make a mountain-fold over this line.

Step 15:
Make a valley-fold over these 2 lines.

Step 12:
Make a mountain-fold over this line.

Step 11:
Make a valley-fold over these 2 lines.

Step 14:
Make an inside reverse fold over these 3 lines. (These lines lay on the edge which you've made in step 13)

Step 13:
Make an inside reverse fold over these 3 lines.

Step 21:
Fold the edge on the right of the pink line to the left by making a valley-fold over this pink line. Make the same fold on the other side of the body.

Step 19:
The back of the model looks like this now.

Step 20:
Hold the model the same as I do. Then, pull the tail to the right, see arrow.

Step 18:
Make an inside reverse fold over these 3 lines.

Step 17:
Make an inside reverse fold over these 3 lines.

Step 22:
Now the model looks like this.

Step 28:
Make a valley-fold over these 2 lines. Now you've made one ear. Make the same folds on the other side of the head.

Step 25:
Hold the model the same as I do. Then press the head of the cat flat with your other hand, see arrow.

Step 26:
Make the pink folding line sharper by pressing the places indicated by the arrows against each other. Do the same on the other side of the head.

Step 24:
Push the pieces indicated by the arrows against each other, in the direction of these arrows. No new folding line has to be made to do this.

Step 23:
Fold the piece below the pink line upwards by making a valley-fold over this line. Make the same fold on the other piece indicated by the arrow.

Step 29:
And the model looks like this from aside.

Step 27:
Now the model looks like this from above.

Step 30:
Press the edge indicated by the arrow inwards by making an inside reverse fold over these 3 lines. Do the same on the other side of the model.

Step 31:
First press the edge indicated by the arrow inwards. Then, make a mountain-fold over the short pink line.

Step 32:
Hold the model the same as I do. Then, press the head a little to the left with your other hand, see arrow.  This is to make the cat's neck a little shorter.

Step 33:
Press the edge indicated by the arrows inwards by  making an inside reverse fold over the 3 pink lines. Do the same on the other side of the model.

Step 35:
Press the leg flat between two fingers, see arrows, by making a mountain-fold over the pink line. Do the same on the 3 other legs.

Step 34:
Curl the tail: Upwards on the place indicated by the arrow below and downwards on the place indicated by the upper arrow.
