Published on Oct 9, 2014 Marmalade (DOB: 07/01/2013) was recently diagnosed with cancer, Marm also tested positive for FIV, which is the likely cause that he became sick so early on in life.Obviously this has been a difficult time for us, but we've always admired Marm's fighting spirit, when we first introduced him to Cole he never backed down and was a tough little kitten, so we began to call him MARMALION! … With chemotherapy in his. UPDATE: Unfortunately the mass was cancerous a high grade lymphoma, we will be consulting with a specialist next week to discuss treatment options for Marmalade…. we know this young, feisty cat will kick cancer's butt! :) Marmalade had to have surgery to remove a mass in his intestines, he'd been vomiting every 3-4 days shortly after we arrived in California... We had been trying different cat foods and he tends to eat too fast as well, so we weren't overly concerned until he began to vomit more frequently and then we knew something wasn't right. Round 1 of the chemo hasn't had much effect on Marmalade, he's a little more sleepy at times but still very active as well! ... he's taking steroids too and his appetite is definitely still there! … He gobbles up all the food we feed him Before your worry too much, Cole was tested for FIV and the result was negative.
