胖貓 = 糖尿病？｜Obese Cat = Diabetes?
雖然作為一隻阿嬤養的胖貓可能憨狀可掬，萌態畢露；但飼料全天候自助任食，甚至貓咪一吃完就補，任由貓咪增胖是將他們置於生命危險之中。
貓咪長期無限制的食用高碳水化合物的乾飼料，容易造成貓咪肥胖，並提高罹患糖尿病、腎臟疾病、泌尿問題、和關節炎的可能。
A chubby cat may be adorable, but providing a dry food buffet for your cat to feast on all day long can put your feline friend’s life in danger. An unlimited supply of starch-based food can easily lead your cat to be overweight, and increases the risk of diabetes, kidney diseases, urinary problems, and arthritis.
貓咪血糖該如何控制？｜ How to control blood glucose level of a cat?
飲食是最好的切入點，將貓咪的主食換成低碳水化合物的主食罐頭，或是直接改吃生肉餐，配合治療，追蹤血糖曲線及胰島素的施打，雙管齊下，都能夠有效的控制貓咪的血糖波動。
Diet is the easiest way to start. By changing their main diet to low-carbohydrate complete cans, or species-appropriate raw meals, you are already more than halfway there. Keep it up with doctor’s treatments, BG curves monitoring, and insulin injections, and your cat’s condition can be under control in no time.
如何計算主食罐的碳水化合物含量？｜How to calculate the amount of carbohydrate in a complete can food?
法規未要求寵物食品標示碳水化合物比例，要如何才能辨別含量是否過高？
通常可以先看產品標示成分是否有添加五穀類或高澱粉類蔬果等原料。
蛋白質、脂肪、纖維、灰份及水份是否全都有標示？沒有的話就是標示不全。
100%減去蛋白質、脂肪、纖維、灰份及水份的百分比後，剩餘多少？ 若數值為負數，恭喜你，廠商的標示完全完全不精確，無法參考；建議你直接跳過他不要購買。
100%減去蛋白質、脂肪、纖維、灰份及水份的佔比後，就是粗略的碳水化合物比例。
If it is not required to label carbs on commercial pet food, how can I know the right amount?
You can start with the ingredient list, if there’s a LONG list of grains, flour, or starchy carb-rich vegetables such as potatoes, the chances are there’s more carb than needed.
Does the label AT LEAST includes protein, fat, fiber, ash and moisture? If not, skip it right away, as the label is not even legitimate.
How much does the analysis add up to? How much does it left, if the number is to take away from 100%? If the final number is negative, congratulations, you can rule out another cheeky brand.
100% take away the percentages of protein, fat, fiber, ash and moisture, all there’s left is the rough percentage of carbohydrate in that can.
你可能想問，罐頭的蛋白質只有 10% 那麼低，那我給貓咪吃 35% 蛋白質的乾飼料不是比較好嗎？｜It says 10% protein on canned food labels, 35% protein on kibble packs, why should I feed them canned food anyway?
因為罐頭含水量高，如果要跟乾飼料比較的話，還得先換算成乾燥物質比例(Dry Matter Basis)才能算數。
乾燥物質比例的計算方式：
100% - 水份% = 整體的乾物%
濕重碳水化合物% ÷ 整體的乾物% = 乾重碳水化合物%
＊蛋白質及脂肪的乾燥物質比例也是上列方式計算。
As the canned food and kibbles have very different moisture content, they cannot be compared like this. You will have to compare them under Dry Matter Basis.
To convert the content of the analysis lists into dry matter:
100% - percentage of moisture = percentage of total dry matter
Then use the percentage of labelled protein ÷ total dry matter = percentage of protein under dry matter basis
Also try this calculation with dry food, and the actual percentage of protein in kibbles could surprise you.
* The percentage of carbohydrate and fat in dry matter can be calculated as the same way above.
貓咪得了糖尿病會好嗎？｜Is feline diabetes curable?
只要是錯誤的飲食所引發的糖尿病問題，若飼主願意積極配合血糖追蹤、胰島素施打、正確的飲食觀念，以及貓咪願意轉食；只要病程還不到無法挽回的地步，都有可能改善或是脫離每日驗血糖及打針的惡夢。
If it is in an early stage, and the BG level is well monitored, insulin injection on-time, and with the right diet, which includes that your cat is willing to cooperate, feline diabetes can be well maintained. It is possible to stop BG monitoring and insulin free at some point if discovered early, but it can always relapse, so it is best to be cautious always.
