...bit me on Sunday. Although he punctured the skin I didn't think much of it 'til yesterday when it started hurting and my hand went red and started swelling up.

No change this morning so I nipped down to the local A&E. One hour later I left having had a tetanus injection and been given a course of antibiotics and some painkillers. Back tomorrow for a followup.
Just wait until I see that bloody cat again.
