here is Skittles +12 number = 564

I gave him 2 units w his can friskies at 9:00 PM
Are the below food safe? I guess I didn't write down enough choices ( my printer isn't hooked yet)
Friskies Turkey & Giblets Dinner pate classic
and for emergency ? Friskies with Beef in gravy savory shreds and also Turkey & Giblets Dinner in home-style Sauce saucesations . Can I mix brands like Friskies & 9-Lives?
I posted above that i have a friend that's a vet, she did say before that Hills MD dry is okay but she didn't say anything about it having a high card count so I do feel better having him on can now, but I do think
I messed up yesterday but not giving him any dry. I just went from dry to can without even realizing I didnt slowly switch him over, plus i did mixed his 1st can w water
Speaking of food, I feed him when he gets his insulin but should I be letting him eat when he wants food in between? At his PM shot ( 9:00 PM), he ate a whole can and just like 10 mins he wanted more food so i did give him more. Today I dont see him drinking as much nor going to the litter box. To me it seems his back legs look worst, but my daughter does agree. I just got home about 20 mins again and he was at the bottom of the stairs, when I left at 10:15 PM he was laying on the top step which makes he think he fell down them. Tonight is the 1st time i have seen him at the bottom ( but we have not been in this apt a whole week yet)
