I’m considering whether to sign up for a care plan for our 5-month-old kitten. It would be around 10 pcm and include worm/flea treatments, as well as next year’s vaccinations, if we stay on it. He’s already had his first two sets of jabs, and will be chipped soon. Does he need worm/flea treatments every month? I’m a first-time cat owner. Thanks for your help.
