The first thing I was able (determined) to do was clean out the piggies. That was the most pressing concern for me as my husband has asthma and was struggling from the off with cleaning them out. It all worked out fine in the end.
Hub has an arthritic knee and struggles with bending. We are forever so grateful to @Qualcast&Flymo for helping with the otherwise impossible cage clean while I was in hospital and then for being instrumental in finding local help for cleaning. I have been worrying about the piggies a lot but there was so little I could do about it myself.
