Measurements of the magnetic properties, the electrical conductivity and the Seebeck effect were performed on single crystals (Cd_{x}Al_{y})[Cr_2]Se_{z} between 77 and 300 K. All samples have a ferromagnetic order with the Curie temperature of 130 K and the paramagnetic Curie-Weiss temperature of 155 K. Both these temperatures do not depend significantly on the Al substitution. The electrical conductivity of single crystals CdCr_2Se_4 doped with Al was p-type and showed the change of log σ versus 1/T slope above 150 K. This fact is interpreted as being due to the onset of impurity conduction and structural defects.
