Hi & welcome to COL
My two kept doing this, I tried all kinds of beds, even the hard ones and Olli persisted in chewing them
(the edges looked like a pie crust)
Until I saw a leather type one in PAH, thought it was worth a try as neither have even attempted to chew the settee.
They both noth have the leather beds and neither have chewed them
I think I have them fooled as they think they are the sette
Its worked anyway so im happy.
