Dear friends; my 15 y.o. cat is chronic renal. she takes 125 ml serum w/lactate every 48 hs. No appetite: I must feed her Recovery & AD 120 ml/day via a seringe in the mouth. The only food she will eat spontaneouly is ND tuna or tuna&salmon. I live in Brazil, these cans are imported, very expensive. The vet told not to feed commercial canned tuna for its sodium content. Question: what if I buy natural tuna or salmon at the fishmonger and give her? Thank you VERY much!

The challenge with chronic kidney disease is that it's often necessary to limit protein intake, but they can be a bit nauseous if their kidney values (BUN and creatinine) are high. Some cats also require supplements of potassium to help keep their electrolytes under control. I don't know specifically what you have available in Brazil with respect to prescription diets, but I usually prescribe either Hill's Science Diet k/d, Purina NF, or Royal Canin renal support. I would start by asking your vet if you could try one of those diets for Sophia - possibly mixed with the A/D to help make it more palatable to her. Ultimately, when it comes to managing cats with kidney disease, it's more important to get them to eat something - anything - over nothing. If you try all of the renal diets and Sophia rejects them all, I would next try any other canned commercial cat food. If she also rejects those, you'll just have to give in and go with the higher protein fish option, such as cooked fresh tuna or salmon. It's not ideal, but what in life is? I hope that everything goes well for Sophia!
