Fermi has always been deathly afraid of our stairs.. but he got the courage to go up them finally! Fermi has arthritis, a common ailment to Flemish Giants. Because of this, Fermi never nears the stairs. He struggles with going down them so we usually have to carry him. Fermi is 2 years old and weighs in at 20 pounds. He’s litterbox trained, sleeps under our bed every night, and has free run of the house. Flemish Giants make WONDERFUL pets. They are the perfect mix between a dog and a cat.
