Do I have to have a Permanent vet for my kitten?

Pets aren't cheap, so if you're concerned about cost do NOT get a kitten.

Your kitten will most likely need to be wormed (unless the place you get the kitten from does that for you) and will require a wellness checkup upon coming home as well as rounds of shots.

At bare minimum, your kitten will need to have rabies vaccinations every 1-3 years depending on your local laws and you'll have other vaccinations that you'll either need to give or be mindful of.

YES it is a good idea to have a vet - emergencies happen all the time and pets get sick, you need to have a vet not only perform vaccinations and checkups but also in case you need them.

There are over the counter worming medications, but it's always best to have a permanent vet as then they will know your animal. It's good to be reminded about vaccinations, you wouldn't want to forget and end up with a very sick animal!

several things you should do : get tested for feline leukemia virus FeLV, and feline immune virus, FIV, as these are top concerns; submit a fecal sample as they may not have worms and the deworming would be a waste of money; if they don't have FeLV or FIV, and are going to be indoor cats, they don't really need vaccinations, just regular check ups (once a year, unless a noticeable change in behavior such as appetite loss or grooming, if a cat stops grooming itself it's usually a very bad sign) as you would go to your doctor for yourself.
