Abyssinians are generally healthy but are prone to gingivitis. If not treated, the more serious periodontitis can develop, causing tissue, bone and tooth loss. Untreated, dental disease can undermine the cat’s overall health. With routine tooth brushing, regular checkups, and periodic professional teeth cleaning, the problem can be minimized. Amyloidosis, a disease thought to be hereditary that affects the kidneys, and PK deficiency, which causes anemia, have been found in some Aby lines.
