Welcome to this wonderful site (if this is your first post). Yes chemo does make our excretions toxic. It is really important to be extra "clean" and careful whiilst on chemo. Your oncology nurses will explain it all to you. As Julia has stated your immune system will definately be impaired and you should remember to protect yourself and others. As for pets - they are our GIFT. Our old German Shepherd was diagnosed with a tumour in his tummy a month after my last diagnosis. We had a choice of a) putting him to sleep b) an operation that he probably wouldn't have made it through and c) taking him home with steriods to "see how he went". I was not prepared to let him go without a fight. So we took him home and gave him the steroids and lots of love. I had to go away from home for 6 weeks to have radiation treatment and amazingly he was still alive on my return. Then it was time for chemo. My wish was for him to be by my side during this tough time - and he was. I finished chemo in June and he passed away at the end of August. When I was really sick from the chemo (toxic and my immune system very low) I didn't have immediate contact with him but I was thankful that he was "around". I am sure that your cats will be of enormous comfort to you during this challenge.XLeonie
