Hi folks This could be totally unrelated to Bob's switch to Lantus, but has anyone else's kitty experienced vomiting and lack of appetite when using the insulin? The problem I've got here is that Bob is currently suffering from a reoccurring illness - an upper respiratory infection (sneezing, runny eyes and nose) - that always makes him lose his appetite and can cause sickness, so I'm not sure if it's just that. He had his usual 1u this morning, but has eaten very little and thrown up a couple of times. Tested him after six hours (he tends to peak around that time the 12 hour cycle) and he was at 18 mmol/L, so no danger of a hypo. Obviously I'll retest before giving him his evening injection. Any advice appreciated.
