Good job in getting your extra sweet kitty Rodney into diet controlled remission.
I know you said he's a picky eater. Here's a link to a topic on
Canned cat food for EUROPEANS and INTERNATIONAL buyers Look for the posts by Dr. Schrodinger and look at her signature. She has a nice link to a food list in her signature.
Useful UK food list for Brits There may be other ideas in that post for food choices for your cat Rodney.
Here are some tips to stay OTJ (off-the-juice, insulin being the juice)
1. Never feed dry - not even treats. If you change wet food types, be 100% sure the new food is also low carb and same low carb % as your current food. Some cats are very carb sensitive and an increase from 3-6% to 8-10% can spike the BG’s. Don’t feed if you aren’t sure!
2. Weigh every 2 weeks to 1 month to watch for weight changes. Too much of a weight gain can cause loss of remission.
3. Measure blood once a week, indefinitely. You want to catch a relapse quickly. Some people only do checks every 2 weeks to a month.
4. No steroids or oral meds with sugar - remind your vet whenever giving you any medication. Always double check.
5. Monitor food intake, peeing and drinking. If increasing, a sign of losing remission.
6. Regular vet checks for infection such as dental , ear or UTI. And get them treated quick!
If your cat does fall out of remission you need to be more aggressive and resolve issues/ back on insulin as soon as possible as the window for a second remission is tight if any. Pancreatitis, hyperthyroid, dental issues are the most common reasons cats fall out of remission.
