Certainly, the cat should not be lifted with a hand beneath its abdomen. The some method as illustrate for a normal cat would be satisfactory.
Some breeders prefer to carry pregnant females with their body in a more vertical plane; one hand handling the front legs up and the other supporting the weight of the hind quarters, so that the cat is in a ‘sitting up’ position.
