Hi Robert,
The cat is surrounded with fiber glass batting. The same stuff that is used for thermal insulation in houses. Obviously, there is no paper backing, just the glass, which has a melt point of about 2000°F. Steel melts around 2500°F or so and starts to glow dull red about 1500°F or so.
So the glass *should* be able to take the heat from the cat.
Jim.
