So i was planning on getting all the exotic animals once I had a decent amount of money which is 7k. So I got the giraffe, moose, alligator but I just can't find the tigers. They used to spawn near the field thats to the left of my base but now they are gone. No tigers come out of the caves they used to be in. I'm confused are they dead or something? I checked the whole map for them too.
