This ferret owner loves his pet so much, that he had it fitted with a pacemaker when it was found to have heart problems. Zelda the ferret belongs to Carl Hobi. He has three of the mammals, and when Zelda fell ill back in December, he rushed her to the vet, where they discovered she had cardiac issues. The vet diagnosed a blockage in Zelda’s heart causing her to need a pacemaker. The surgery would cost Hobi $4,000. The tiny pacemaker had to be specially ordered and chances of success were slim.
