If you think that your cat has a hairball problem, just be thankful that it's not as big as Ty's. The 400-lb tiger had to have surgery to remove a 4-lb hairball!
Veterinary surgeons in Tampa Bay were called in after Ty the tiger failed to cough up the monster obstruction all by himself. [...]
The vets initially performed an ultrasound and took X-rays before using a endoscope with a camera to gauge the size of the hairball. But it was so big, they determined there was no chance of retrieving it that way and an operation would be needed.
