So maybe put a reminder on your July calendar to go over the medication regimen with D?
If I used a calendar lol. I am the little slips of paper all over the place type haha. Anyway it's very simple. Prepare 1st meal. Separate about 0.3 oz of the 1st meal, add the lactulose and the prednisolone, stir to mix well, dust forti flora over it and put it in front of her. If she leaves any (she usually doesn't) dust a little more forti flora over it to ensure she gets it all. Then put the remainder of her meal in her meal spot.
Hopefully, she won't need to know. I've medicated her cats at various times over the years when she goes away, but she goes away, on vacations, long ones. I never do that. She's a lot more casual about things than I am.
Once I started my job at the city, and didn't have the flexibility, she started using a cattery instead. She used to try to get me to take the cats to my place, I always refused. I told her cats are happier in their own homes. Even this time, she asked me several times wouldn't I rather she brought Queen Eva to her house and I said no, Queen Eva will be far better off, even alone, at her own house, than in a strange house with a strange cat. Funny how some people really don't seem to understand that.
But she is a very good friend and I am grateful for her in my life. I am grateful to myself too, for her in my life, because I was the one who initiated the friendship. She responded favorably and now we've been friends for 19 years.
