Hello, I was wondering if any of you are giving liquid leukeran to your kitties. Mine has been on it for about 1.5 months. Yesterday, as I was brushing away a mat from his chest, I noticed a very dark red/purplish lesion. The fur in the area just all clumped off and it was scabby and blistery. I took him to ER and they said it could be due to his prednisolone/leukeran combo that he's on, since they can both cause suppression of his immune system. That maybe he got a cut or something that turned into an infection. It was right in the area where the medication drips from him spitting or not swallowing it all. So I wonder if the chemicals in the leukeran can cause scalding or chemical burns to the skin. I'm taking him into his regular vet tomorrow, but I was curious to know if anyone out there has experienced this.
