I have a healthy short-haired cat called Frodo, who likes cat food with mackerel and sardines (Applaws). He is on a combined dry and wet food diet. One tin of wet food is about 70 g; the rest is dry food, Eukanuba. Now he weighs 4500 kg and is about 11 months old. My question is: is it generally unsafe to give him cat food brands made of boiled mackerel and sardines, even in addition to chicken-based Eukanuba dry food? Or is it safe, but not every day/once a week/once a month? Should I supplement vitamin E or not (Eukanuba contains vitamin E, but will he get enough of that when also fed this fish wet food?)? I need to know, my cat is presently a healthy, active, happy cat, and I do not want to do anything wrong with his feeding. AnnaHi Anna,Thats an excellent and very responsible question. You are right that Applaws Mackerel with Sardine in Broth is a complementary food, which means it is not nutritionally complete on its own. While oily fish such as sardines and mackerel provide valuable omega-3 fatty acids, they also contain high levels of unsaturated fats that can predispose cats to pansteatitis if fed too frequently without sufficient antioxidant protection, mainly vitamin E. This condition, sometimes called yellow fat disease, causes painful inflammation of fat tissue when oxidative damage occurs.Since Frodos main diet is a complete, balanced formula like Eukanuba, it already supplies the necessary vitamin E and other nutrients to keep his fatty acids in check. Offering a small portion of the Applaws fish variety once or twice a week is perfectly safe for a healthy young cat and adds some enjoyable variety to his diet. Feeding it daily or as a large part of his calorie intake, however, could unbalance the diet over time. Supplementing vitamin E separately is not recommended unless advised by a veterinarian, as excessive vitamin E can also disrupt nutrient balance.Think of the fish tins as a treat or side dish rather than a staple meal. With Eukanuba as his main food and Applaws given occasionally, Frodos diet remains both safe and enjoyable. Youre doing a great job staying informed and protecting his long-term health.

James barely steps outside just the windowsill. - CharlotteHi Charlotte,Thats a very good question, and one many cat parents share. Even indoor cats like James can occasionally be at risk for ticks, though the likelihood is much lower compared to outdoor cats. Ticks can enter the home by hitching a ride on people, other pets, or even through open windows and doors. In some regions where ticks are abundant year-round, this small chance can still lead to exposure, especially if wildlife such as rodents or birds frequent areas near your home.The best approach is to consider your local risk level and James lifestyle. If you live in an area where tick-borne diseases such as Cytauxzoon felis or Borrelia burgdorferi are prevalent, your veterinarian may recommend preventive treatment even for mostly indoor cats. These products are generally safe when prescribed correctly and help protect against the rare but serious complications ticks can cause. This is especially relevant because some tick species also transmit zoonotic diseases, which can affect humans. If James exposure risk is minimal, regular tick checks and maintaining a secure indoor environment may be sufficient. Your local veterinarian remains your best guide, as they are familiar with the parasites and disease risks in your area.Sincerely, Dr. PaolaThis article is a part of our weekly Ask Dr. Paola series Read last weeks questions here: November 3, 2025 Find the full list of past articles here Click here to submit a question Sign up for our weekly newsletter below to get Dr. Paolas advice sent straight to your inbox.
