Are these actual cat seals?

It Is not a cat box but you would never tell the o rings apart from the genuine - perhaps they are made at the same factory..

A cost effective kit to keep on my service truck. Has gotten me out of a bind several times.

Looks to be a good complete oring kit. Orfs, orb, flange orings. Only thing that would make the kit be better is the compartments had labels on style & size.
