I wonder if you could give me any suggestions regarding my 10-year-old cat Ringlings behavior. We lost our 22-year-old Siamese a month ago, who was Ringlings lifelong friend. Ever since he died, Ringling has gotten very clingy and vocal, following me around, continually begging to be petted and held. She seems to need constant attention and reassurance. She has also thrown up several times in the last weeks, something she has not done before.
