A malnourished, abused tiger needs care. With care, under your roof, they can grow healthy and strong. They may appreciate petting, nourishing, patronization. For months, especially if they were struggling.
But if you succeed — if you finally nurse a tiger back to full health — it will be a full tiger again. If you keep it under your roof, it will be restless. If you patronize it the same way, it may retaliate. The best thing you can do is let it go free, maybe visit, and be around if it needs you again, realizing it may never again need or want your help. Or it might. Hard to tell, with tigers.
Doesn’t mean it was ever trying to “trick” you when it was sick and begging for help. Maybe the tiger didn’t even realize what a healthy tiger was until it became one.
A lot of people are kinda like tigers.
