Sue,
I will second the switch for Sammy over to Levemir...I really like the way Autumn is responding to it as well..I've tried Lantus on 3 cats so far now and the only one it seemed to work well for was Maxwell and I honestly think he would have gone OTJ on diet alone. For a long term diabetic lev just seems to be a better choice.
