Poor guy! It could be a sign of pain or trauma from the event including head or neck trauma, or a side effect of pain medication. If he was bleeding did they find the source of it? Was he given any medications at the clinic (pain medication?) or to take home? Was he appropriate mentally there and then has declined? The problem with kittys getting attacked is that the attacker often shakes them while biting. This can create a lot of shear trauma under the skin that is initially not seen. If no meds have been given i would worry about pain or head trauma. I would recommend calling the clinic that saw him to report this change. The safest thing for these patients is for them to be hospitalized for monitoring because not all problems show up right away. If head trauma is suspected medications may need to be given for this. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!
