Kitty dramas

I am worried about our small cat (he's not very small, really, but to me he will always be a kitten). He has another abscess on his head which has swollen up today, so we'll have to take him to the vet tomorrow. We had endless dramas over Christmas when he got in a fight and developed a big abscess by one ear - many trips to the after-hours vet, many stays in kitty hospital and a week or so of a small, furry being wandering around our house looking like Frankenstein's monster. Hopefully that will not be the case this time. I am not looking forward to the vet trip, though - the vet always looks disapprovingly at Mink's girth and tells me off for not weighing him more regularly. He's not obese, but he's certainly plumper than ideal.
