Hi, Sue to answer your questions.
When this all started last year Loki went from 17 lbs to 8 , he is now 10 to 11. He always was a grazer when I left the dry food out but now with only wet, he comes and finds me about every 4 hrs or so for food. He is now almost 16 (next month) and has not been a really active cat.
He is not really getting exercise right now, in the summer he goes out and hunts and also hangs out there chasing things like dragon flies etc. I do try and play with him every night so he moves around some.
I started adding warm water last week when you had mentioned it, also I add it for the other 2 cats in their food, they are also on wet only now.
Loki does not eat with them because one of them is a bully and won't let him eat. The other is fine, he eats and leaves. Loki seems to like eating alone.
Cannot think of what else I can add. I will do a +6 daily from now on to see if there is a pattern. Somedays it may not be possible but will try to get most days done.
Thanks
