hi everyone , my Guinea pig Gandalf was neutered 3 weeks ago and this evening I've noticed he has a slight swelling on one side , I did a bit of looking on the net , and it seems abcesess are quite common, I'm going to phone first thing in the morning and hopefully get him into a appointment tommroow, I'm really worried though. He is absolutely fine I'm himself, putting weight on , drinking, eating, popcorn, shovelling his nuggets and veg down and doing laps around.
