took him to the vet this afternoon, the lump was bigger again this morning so thought I better! The vet seemed a little concerned that it has presented differently to last time, but has prescribed a course of antibiotics and if he isn't getting better by Monday have to take him back so they can investigate further. He did talk about some kind of fungus they can get in their mouth that can have cancer-like symptoms, i was like uhh..ok...lol. I don't think it would be anything sinister like cancer though because it only happened overnight. He was really nice and even put it through as a repeat consult (even though the other one was 4 months ago!) so was a fair bit cheaper than it would have been

So fingers crossed it starts looking better over the weekend!
