Pet Care Needed

We have three lady cats, two savannahs (Athena and Vienna) and one orange failed barn cat (Biscuit). Biscuit, the orange cat, needs a pill once a day, preferably in the morning. We are able to trick her into taking the pill with treats. The other two do not have any special requirements. Just food, water, and litter. Biscuit is usually shy, but nice as long as you don't make a bee line for her head (she has a degree of blindness). Vienna is a sweetie pie. Athena is our terror - she doesn't like to be pet and will start tiffs with the other cats (but then gets scared usually). They all like catnip and wand toys.
