each having a first predetermined length and a loop 26 formed on each of the ends thereof it should be noted that the rods of the present invention may very well refer to a heavy gauge wire or the like in the preferred embodiment the loop includes an end of the rod bent to form a closed loop configuration and further twisted with itself for strength as shown in fig4 the loops of first ends of the pivot rods are spacedly and pivotally coupled about a common horizontally oriented wire of the cage such wire resides at a height common to the upper peripheral edge of the dish on the other hand the loops of second ends of the pivot rods are each fixedly coupled to associated separated apertures of the dish the second ends may be fixedly coupled to the dish via glue a flange or any other suitable means during use the pivot rods remain in parallel relationship and define a plane which always contains the entire upper peripheral edge of the dish as such the pivot rods and dish are adapted to pivot about the horizontally oriented wire of the cage to which the pivot rods are coupled finally a rigid linear lift rod 28 is provided having a second predetermined length which is greater than the first predetermined length the lift rod has a pair of ends one of which has a loop formed thereon similar to the pivot rods the loop of the lift rod is pivotally coupled to a remaining one of the apertures of the dish as.
