I have female cat about 5 years old , I took her to the VET for speying , and i told the Doctor , she lost some weight and was drinking more than usual . The Doctor told me , she had diabetes , and prescribed Pro-Zink 2 units , once a day. A few days later my cat started to eat like crazy , and started to drink more. I took her back to the VET for check up , 3 weeks later , and after a blood check , she told me to double the insulin to 2 units , too times a day . It is going on for another 3 weeks now , and there are no changes , she is always very hungry , drinks a lot of water , and the litter box is full with large chunks of sticky pee. I have 4 cats , she is the mother of the other 3. She eats everybody's leftovers and most of the dry food too. I regret started her on Insulin without trying to change their diet first , but I trusted the Doctor' advice. It's because her symptomes are getting worst , the more Insulin she gets , she eats and drinks more. Did anybody experienced the same , and what did you do ??? IThis situation is new to me , I did not have any experience with diabetes , I'm still looking up all the information on it . Please give me advice , I wanto do my best for my pets !!!!!!!!! Thank You!!!!
