23. By passive transfer of maternal antibodies through the colostrum.

24. After the first 16 hours of life.

25. Tattooing, ear tag placement, and microchip implantation are commonly used methods of identification in the cat.

26. Cats require diets high in protein and fat but low in carbohydrate.

27. Association of American Feed Control Officials.

28. Calculation of the nutritional content of a product’s ingredient list, on chemical analysis of the feed’s nutritional content, or by feeding trials.

29. 60-80 kcal/kg body weight per day

30. 250 kcal/kg body weight per day

31. Severe hepatocellular lipid accumulation which leads to impairment of liver function and other metabolic consequences. Anorexia and rapid weight loss can result in this life-threatening illness, especially in obese cat.

32. Feline lower urinary tract disease.

33. hematuria, dysuria, pollakuria, straining while in the litter box.

34. Magnesium ammonium phosphate crystals.

35. Urine acidity. Struvite crystals do not develop in acid urine.

36. A product formed from the hydrolysis of animal tissues and by-products that contain phosphoric acid, which serves as a urinary acidifier. It is sprayed on dry cat food and increases the palatability of the food.

37. Overcrowding.

38. Feline herpesvirus (FHV-I) and feline calicivirus (FCV)

39. False. Transplacental transmission does not occur with neither FHV-I nor FCV.

40. Direct viral contact through nasal and ocular secretions and via fomites.

41. Feline enteric Coronavirus (FECV) and feline infectious peritonitis virus (FIPV). FIPV is virulent, FECV is ubiquitous and avirulent.

42. False. FIPV can not be distinguished from FECV serologically.

43. Replication of FECV takes place in enterocytes, where replication of FIPV takes place in macrophages.

44. FIPV is a systemic intracellular pathogen, but systemic antibodies are not protective. Antibody production may enhance the disease complexes formed when antibodies bind with virus result in increase uptake of the virus by macrophages, where further replication occurs.
