My 2-3 month kitten is sleeping all day after her first vaccination shot!?

My 2 almost 3 month kitten has got her first shot today, after the shot she slept all day also she would play with her favorite toy then walk away ( she never does that ). I'm not sure if this is normal behavior for a small kitten getting a vaccine. PLEASE HELP!!

Ours did the exact same thing. She slept and was unwilling to play for the first day and a half after her second shot. It shouldn't be anything to worry about.

Thank you for the reply!!

No problem. A lot of vets will tell you to expect a kitten to be lethargic after their shots for a day or so. According to our vet it is worth worrying about if they stop eating, drinking, going to the bathroom for any amount of time.
