What should I do about my cat problems?

someone or somebody has mistreated the poor thing,could you keep her inside for a while and away from other cats,also it may be there mating time our cat acted "funny" like that not as bad.but we kept him inside for about a week(he hated every minute of that he is a real stud) he settled down considerately,also if you have time take him to vet to get checked,could have been bitten by other animal who has rabies,are shots up to date?better to be safe than have a sick on your hands.good luck
