Almost everytime my leo Samson goes to get a cricket, he'll pause and slowly walk up and he'll pause for a bit. If he pauses for a while, his tail will start to wag, starting from the tip then it actually starts to vibrate, then he'll pounce and it will be over. This usually happens with each cricket but not always and he only does this when he's getting his crickets. Does anyone have leos who do this?
