A flexible, heated, non-allergenic mat particularly adapted for use with animals has a flexible layer of recycled crumb rubber formed under heat and pressure with resin. A reflective sheet is disposed in the flexible layer for reflecting heat. A wire forming a heating element is disposed in the flexible layer above the reflective sheet for heating the mat in response to an applied electric current. A plug and socket may be formed in an edge of the flexible layer so that adjacent mats may be electrically coupled to form a larger heated surface.

[ What is claimed and desired to be secured is:] [1.]1. A first heated mat having top and bottom surfaces, said mat comprising:a non-allergenic layer of flexible material formed by heating crumb rubber and resin under pressure;an electrical resistance heating element disposed in said layer of flexible material, said heating element increasing in temperature in response to an applied electric current;a layer of structurally reinforcing mesh material disposed in said layer of flexible material and coupled to said heating element prior to forming said layer of flexible material; andsaid mat having an edge disposed between said top and bottom surfaces, said edge comprising one or more protrusions oriented generally in the plane of said top and bottom surfaces, said protrusions being configured and arranged to index in structural interference with protrusions of an adjacent mat, thereby to prevent relative motion between mats in a direction parallel to the common edge of said mats.
