our lovely boy Sherlock who adopted us around Christmas has just had his 2nd set of vaccinations (we had to start from scratch as we didn't know what he'd had done). First set of jabs had him a bit listless for a day but the 2nd set done friday seem to have hit him for six 
He is listless, off his food and sleeping much more. Awake seems to see him droopy and he is limping, as if his legs are hurting and he yowled when I lifted him up to take him downstairs as he couldn't manage them
He is normally such a character but he seems poorly and depressed. Has anyone elses cat had such a reactions to their jabs?
