Is my cat out of sorts because of his jab?

[Pointlessfan]

In a nutshell, he had his annual check up and jab yesterday and has been asleep in his bed pretty much ever since. I've seen him eat twice, a small amount each time, and he's had a wee but that's it. He has just slept or lay there looking grumpy.
Could it be that the jab has made him feel off colour like it does when people have them?

It surely could. My lad is always just a little out of sorts after his booster - for about 24-36 hours. Have you noticed this before?

No never! I'm just trying to decide whether to be worried or not! Thanks though, that's probably all it is.
