Glad to hear you already have the Feliway diffusers covered. :-)Wonderful suggestions. I will discuss the iron issue with my vet and see what he thinks...or at the very least he can run bloodwork on Meowki and see how his levels are doing.
If your cat has a tough time with his pill form, I know that another option is to have them do injections once every so many months.
I actually have Feliway in my house already- love the stuff....have been using it religiously for close to 4yrs now. I first used it it for Malina (she was very anxious at night) and I still use it today with the other two cats (it really helps with high strung cats). I believe the main ingredient is valerian root extract...which I would love to know if anyone has tried making their own.
We used to have a heck of a time trying to get meds down our FIV+ cat. Thank goodness he suddenly developed a taste for baby food, which seems to sufficiently disguise the taste of whatever the vet said was okay to dump into his food!
