Cat Care: Fleas & Parasites : Symptoms of Heartworms in Cats

[chabella123]

My cats syptoms: sometimes deep coughing (nothing comes out), throwing up (food, or half digested food, or just yellow liquid)- and can happen 1.3 times a day, or on bad days 5 times. Some days nothing. (he gets speical vet food which he has been on for many years) I see the syptoms are getting worse. he has trouble with nr 2. tries in his litter, & i hear gassy sounds, sometimes looks like diarehha, and then he does on our floors, and hard bowl. so im very confused!! Any help? PS. Male cat of 8
