Took 9wk old kitten in for first jabs this morning. He was fine when we got back but I went out at 11 and he was hiding under the sofa and hasn't yet emerged. Is this normal? Prior to going to the vets he was bold as brass but now is hiding in the furthest recess of the sofa which means I couldnt haul him out without furniture moving. Don't want to disturb him if he is just sleeping off his jabs.
Is this to be expected?
