Suzanna Didn't Feel Well

On Saturday Suzanna had a very difficult time at the litter box. She was somewhat constipated to say the least. She would try to 'go' but nothing happened. Then she would scratch the litter and the surrounding area as though she was covering something up but there was nothing to cover. She went through that ritual several times. I gave her some store bought hairball remedy solution that I had on hand. Come Sunday morning, the problem still existed. And the ritual continued. I was planning on a trip to the vet for Monday morning. But, my wonderful brother-in-law who is a cat lover, told me to put a few drops of mineral oil in her food. So I made a mad dash for the drug store. First I put some on my finger then near her nose, just to see her reaction. She licked it right off my finger! I put 3 drops in her food. She ate it all up then couldn't get to the litter box fast enough. This time it was for real. I gave her the same amount the next day with the same results. It is now Tuesday and she is back to her normal, or should I say regular, self.
