Kitten different after vaccination

[dinosaursgorawrrr]

Hi,
Dkitten went for his first vaccination on Tuesday at 15 weeks old.
Before we left he was his usual bouncy self. Got home and he slept most of the day but still sprinted around in the evening.
Yesterday he was okay, still sleeping a lot but no other issues.
Today he woke up meowing for his food and ate it all. He then had a play for a hour and fell asleep. He's slept pretty much all day other than the odd 20 - 30 minute play but he's not as enthusiastic as normal. He's not even beating the dogs up or nipping us which is worrying me slightly.
It's been just over 48 hours so I'd expected him to be okay by now. The oddest part is ever since he got home from the vets he has slept downstairs on his bed rather than in my room where he's slept since we picked him up.

Has anyone else experienced the same thing? It's like having a baby all over again 😩

Picture for tax

Yes, mine is always out of sorts and sleeps more for a few days after her annual vaccs.

He’s a cutie! Hope he soon bounces back to his usual self.

It's normal, but if he doesn't pick up after 48 hours, pop him back to the vet for a check up.

He was vaccinated at 10:30am so it's been over 48 hours. He still looks alert when he's awake but falls asleep again really quickly. I will ring the vets in the morning if he's still not better. He just looks so sad 😞

Yes - it's probably nothing but best to be safe
