@margo,
Well, I will call vet and discuss long-term rates!!!
I think I need to give my friends a rest before asking them if they'd consider taking her sometimes. I think them taking her every fortnight is a bit too much for everyone....including me.
With the vet I just have to move cat, meds and food.
With them I have to move cat, scratching post, two litter trays, litter, food, meds, my quilt.
IF they offered, I'd leave stuff down there permanently...but I'll let the dust settle a bit before asking.
