I've had a random ad pop up for this, and looking into it I think I'd like to try it. I've put all Sparklingcat's details in and it says the cost of feeding her would be £1.89 a day, and that she would only need 1 pouch a day?
Shes 3kg, skinny with a hyperactive thyroid (which she has tablets for) and about 16. She currently wolfs through 4 pouches a day of 'Felix as Good as it Looks'.
Anyone got any experience? There's a 20% off trial but just not sure.
