When adopted, Tigger was skinny with severely matted fur and drank a lot of water. Sadly, a trip to the vet revealed that Tigger was suffering from kidney failure. He was immediately put on a special diet along with medication and started to gain weight.
Unfortunately, bad news struck again a few months ago - the vet found multiple tumors in his body, according to Yahoo News. Because of Tigger's age, he's not a candidate for surgery, leaving him with a limited amount of time to live. So Buisch and her boyfriend decided to make Tigger a bucket list filled with adventures, documenting every step of his journey on his Facebook page.
