For a gorgeous girl like Kate, male pets come and male pets go. There is no need for her to keep underperforming males when she has a lineup of men waiting to grovel at her feet like good subservient piggies. Like this new male that she is evaluating to see if he is worthy of serving her including the always important task of licking her shoes clean and worshipping her feet. Thats important to Kate as she cant be expected to walk around in dirty high heels, and plus she loves watching men grovel on the floor like pigs struggling to clean her shoes.
