Ingredients to avoid when cooking for your cat
- Tomatoes – a small amount of ripe tomato is unlikely to cause any problems, but green tomatoes can cause serious stomach upsets and even heart problems, so it’s best to avoid them.
- Onions (and garlic to a lesser degree) – can cause blood problems including anaemia. Again small amounts are very unlikely to cause any problems, but to be on the safe side I only use small amounts of garlic and very little onion in my recipes.
- Grapes and raisins – both can cause very serious illness including kidney problems, and large amounts have been known to be fatal, so avoid wherever possible.
- Mushrooms – best avoided as some cats will not tolerate mushrooms well and they can cause serious toxicity.
- Raw fish – regular feeding can lead to a vitamin B deficiency, so all fish should be cooked.
- Liver – liver contains a lot of vitamin A and if you feed your cat a diet rich in liver every day, this vitamin can cause serious bone problems. However, liver-based meals are fine as long as they are occasional and are only fed once a week or less.
