We should only go ahead with the blanket swap procedure if we're confident that the new kitten is negative for panleuk, as it's highly contagious, correct? Do the vaccines eliminate the virus completely, or is there a possibility that it can 'hide' or 'move' within the cat? If the kitten has been tested and vaccinated, is a two-week quarantine still necessary? As the article mentions, it's quite likely that after just a week, the little one will be eager to leave the confinement and explore the house. In that case, is it okay to place the kitten in a cat backpack and enjoy a safe walk in the park together, using a leash for extra security? Since I work from home and have a 14-year-old resident cat, I'm thinking of placing the new kitten in the bathroom. I’m curious about how often I should spend time with the kitten and whether I should wash my hands after playing with it to keep my resident cat safe. Any advice would be appreciated!
