If you give a cat medicine she will spit it out on you. She will also get mad at you. If you try to trick her and put it in milk she will sniff the milk and not drink.
Eventually she will forgive and fall asleep upside down on your tummy.
And just for clarification Pigeon is not a demon cat and she does not have rabies. She got fixed and when I give her medicine she makes her mouth foam up so she can more easily spit on me.
