Side effects from jabs

[nowayjose1]

Hello,

My two kittens went for their first jabs on Friday. All seemed fine however since yesterday (Monday) one of them seems really subdued. He is still eating and using his litter tray. He is just sleeping ALOT compared to the other one, doesn't want to play etc.

My older cat sometimes gets a little bit subdued after his jab but normally a day after not a couple of days later.

I'm thinking maybe this is a delayed reaction to the jab? A bit like when humans get the flu jab it sometimes doesn't come out until a few days later?

If he is the same tomorrow I will call the vet. Anyone experienced the same? X
