You really are doing a marvelous job, honey. Consider that you and your hubby are also going through a form of greiving, and that in itself tends to make our minds lay all kinds of trips on us. So sit back (when you can ), do something for you that you enjoy - a candle lit bath, a moment with a good book, or time in prayer or meditation. I wondered how you are giving the shots - do they tell you to give them in the loose skin behind the head? Having never done that myself, I ask out of curiousity, not as an advisor. However, Dad has vetted many animals in his day and tells me for cats that's the place - my vet says the same. Never hesitate to call your vet for guidance and support - after all, they're there for us as well!!
Much love and many prayers for you and yours - and many thanks for taking the time out of your busy life to inquire about Grasshopper. You're quite the delightful being. Love, Ko & Grasshopper
