what i like about the royal canin is it prevents against both type of crystals, also the vet said the science cd makes them fat, well my lexie needs to loose weight not gain it, and even though she said it would be fine to put her straight on that i have to really wonder, as those crystals need to be dissolved, she seems to think they will be fine, but there is always that bit of doubt, besides i cannot afford any more testing right now,we can only buy it at our vets but i will see if they do offer a small bag, probably a good idea,the only good thing about science is their money back guarantee. :) Thanks for your input, as i am so confused as which way to go really, but i had better make my mind up soon i guess, the other good thing is the science comes in bigger bags, so less trips to the vet to pick it up and is readily available, not sure if royal has to be ordered or not.
Has anyone tried the new purina natural blends,? well it is new here anyhow, it has cranberries in it, which is good for keeping urinary health up to scratch, my other cats really like it, again it is the most expensive food in the supermarket you can buy.,even more so than the excellence i had Lexie on,it was especially formulated for urinary tract care and has no preservs, colours etc, but according to the vet it does not lower the PH level , so that is why Lexie cannot stay on them, pity as she loved them so much and was very content on them,still my others love them too.
