Skin and digestive diseases are the most common problems encountered in cats. A six-month-old domestic cat with a body weight of 1.42 kg experienced problems with the skin and digestive system at the same time. Cases of cats complain that they often scratch and excrete worms when defecating, the feces are yellow and have a paste-like consistency. This research aims to determine the disease agent and intensity of infection that attacks cats so that appropriate treatment can be provided. On physical examination, alopecia, hyperkeratosis, crusting and scales were found on the head, bilateral ears, neck and elbow area. Supporting examinations carried out were skin examination using skin scraping, trichogram, cytological examination using the tape acetate method and otic swab with diffquick staining as well as fecal examination using the floating method and counting worm eggs using the Mc Master method. The diagnosis is confirmed based on the history, physical examination, and examination with results of scabiosis and toxocaryosis. The causative therapy used in this case was ivermectin (Ivomec®) injection at a dose of 300μg/kg BW subcutaneously given three times on days 0, 7 and 14 and pyrantel pamoate (Combantrin®) therapy at a dose of 25 mg/kg BW orally. Symptomatic therapy uses intramuscular injection of diphenhydramine HCl (2 mg/kg BW) and (chlorpeniramine maleate®) at a dose of 2 mg/head given 2x¼ orally given for three days, followed by supportive therapy given multivitamins and minerals (Caviplex®) given once a day orally for seven days. Topical therapy is given with sulfur soap to bathe cats at least once a week. The cat showed good progress starting from the third day, the level of pruritus decreased, then on the fourth day the cat did not expel worms from the anus and the stomach did not look as enlarged as when it was first examined, and on the sixth day it started to show hair growth, alopecia, crusting and hyperkeratosis began to decrease. After administering ivermectin the second time, the cat's case began to improve with the level of pruritus decreasing and the hair slowly growing. After the third injection, namely on the fourteenth day, the cat named Bolu was returned to its owner with improved skin condition and no longer scratching. Based on the history, physical examination and laboratory examination, the cat was given therapy by administering antihistamines, antiparasitics, worm medicine, as well as support by administering vitamins and topical use of sulfur soap. It is important for cat owners to consistently bathe their cats and give them regular deworming medication to prevent recurrent infections.
