Sabre-toothed kyatt are found at the northern part of the Rellekka Hunter area. Create a pitfall trap by using one set of logs from a nearby dead tree with a knife on your tool belt. Click on one of the kyatt to tease them, which makes them attack and follow you around. Walk over to your set up pitfall trap with the kyatt right behind you and jump over it. The kyatt will either walk over it and fall in, or it will jump over as well. If it jumps over, set up a new trap at a new spot (they won't go over the same pitfall trap twice in a row) and repeat the process until the kyatt falls in. Collect a pair of big bones and either tatty kyatt fur or kyatt fur. If you get tatty fur, drop it and bury the bones, then continue to collect the non-tatty fur to sell on the Grand Exchange.
