Thought I would make an update. One of the students must have thought about it over night. This was her reasoning on why she thought the Panther killed the squirrel.
1. Although the Panther loved the squirrel, he might have just been caught up in the moment, and accidentally killed his friend.
2. While watching the video, she noticed there we're 5 wolves, but the Panther had scratched 6 times, therefore the Panther scratched one more thing.
3. When the scene ends, the panther is standing looking at the squirrel, and there is a scratch going down through its body, at the very right angle that the Panthers claws could have gone through the squirrels body
That is it, do with the new information as you will.
