Homemade Tuna Cat Treats Your Cat Will Go Crazy For

I’m so excited to share this recipe for homemade cat treats with you. I’m not usually one to blow my own trumpet but I really think I’ve come up with something rather special here – two-ingredient tuna cat treats, that take just minutes to make, cats go wild for, and are grain, gluten and dairy free!

They came about because I’ve started to do a bit of clicker training with Lyra and Lola to keep them entertained and occupied, and have been trying to work out what I can give them as a reward. Commercial treats like dreamies went down well, but I couldn’t shake the feeling that they were full of all sorts of mystery ingredients, and pretty carbohydrate heavy. I briefly switched to scraps of ham and cheese, which were also a hit (more with Lola than fussy-eater Lyra), but were really salty and calorific and probably not the sort of thing I should be feeding them regularly.

Then I tried tinned tuna, which was another winner, but I ended up with flakes of tuna ALL over the house – NIGHTMARE! (There is still a key on my piano which isn’t working because there is dried tuna down the sides of it, and I’m dreading when the piano tuner comes to fix it next week and asks me why!).

Finally, I scoured the internet looking for recipes I could make at home, but all of the ones I could find relied heavily on the very grains and cereals that I’d tried to steer away from in the dreamies. So I decided to come up with my own recipe, and let me tell you – they have gone down a storm!

Making these treats was such a fun activity to do with the cats – Lyra and Lola loved ‘helping’ me in the kitchen (read: trying to lick EVERYTHING at EVERY opportunity!). And even fussy eater Lyra now goes doo-lally for them.

For those of you that are whizzes in the kitchen, you’ll probably recognise the method… this is essentially a tuna meringue, without the sugar.

Mull that one over… or let’s just get straight on with the recipe!

Two Ingredient, Grain-Free Tuna Cat Treats

Whip up a batch of homemade tuna cat treats your cat will LOVE – best of all, they’re grain, gluten and dairy free!

Prep Time 10 minutes
Cook Time 25 minutes
Total Time 35 minutes
Servings 50 cat treats


  • 1 egg
  • 1 tin tuna in spring water or oil, thoroughly drained (approx 120g / 4oz)


  1. Preheat your oven to 170C / 330F and line a baking sheet with greaseproof paper or baking parchment. 

  2. Crack open the egg and separate the white from the yolk. Discard the yolk and place the white in a large mixing bowl.

  3. Using a hand or electric whisk, beat the egg white until stiff peaks form when the whisk is removed. Set to one side.

  4. Empty the can of tuna into the bowl of your blender (I find a mini blender works perfectly for this task). Add two tablespoons of the whisked egg white to the tuna, then blend thoroughly until the mixture is a smooth paste and there are no flakes or lumps.

  5. Using a spatula, remove the tuna paste mixture from your blender, and fold it gently into your remaining whisked egg white. Take care not to knock too much air out of the mixture while you are combining the two.

  6. Transfer the resulting mix into a piping bag with a small star nozzle attachment. Pipe the mixture into small rounds on the parchment-lined baking sheet. Take care not to make the swirls too large (as this would make it tricky for your cat to eat the treats).

  7. Place in the oven for 20-25 minutes, until the treats feel dry to the touch and dislodge easily from the baking parchment. Transfer to a wire rack to cool, and then into airtight jars for storage. If kept in a cool and dry cupboard, they should store well for up to 2 weeks.

The resulting nuggets of tuna-ey goodness actually get a little harder once they are out of the oven and fully cool. The final result is a crunchy, tuna snack that is so good – shameful admission – that we’ve actually started helping ourselves to the odd one here at Supakit HQ! They’re a little on the dry side for human tastes, but I can’t help feeling they’d be the perfect savoury bar snack to accompany a dry martini. Shh… don’t tell anyone…

Don’t forget that these are still treats – so they shouldn’t replace your cat’s regular diet. Treat them like the treats they are, and your cat will soon realise that when they get one they must have been really good.

The recipe should also work with other types of tinned fish like salmon or mackerel, although I haven’t tried it yet. If you do, please let me know in the comments below how you get on. I’d be fascinated to hear!


Happy baking,

  • I was wondering how long these keep for before they go bad? And do you keep them in the fridge or just an air-tight container? Thanks!

    • Hi Sara!

      If stored in a cool, dry place they should keep well for up to 2 weeks. I find that the fridge air is a little too moist for them so I’d recommend an air-tight container in a cool cupboard.

      Happy baking!


    • Hi Mary,

      You absolutely can, and I did make one batch like this while I was testing the recipe. The egg yolk makes the finished result chewier – a bit like a teeny-weeny tuna omelette! Our cat testers still ate them, but they didn’t keep as long, just a day or so, before they started to get soft. I hope that helps! If you do try them let us know how you get on!

  • This seems fantastic. Is it necessary to blend the meat up to have no chunks? Currently my blender is AWOL. Thanks for the recipe

    • Hi Alycia,

      Thanks for your lovely comment! It does help to blend the tuna up so that it mixes in with the egg white mixture and pipes onto the tray easily, but you could just as easily use a mortar and pestle to give it a gentle pounding and break it down a bit. Let me know how you get on!

  • I found your recipe by chance. I didn’t want to waste any more money on store bought treats. I am so glad to find your recipe. Thank you for posting it.

    • What an interesting idea! I haven’t baked with catnip before but I don’t see why not, I may have to give that a go and report back!

    • Hi Amy,

      I haven’t tried it myself but it definitely could work! I’d go for as lean (low fat) a cat food you can find as otherwise the oils might ooze out during baking. Then again, that might be a happy accident, frying the treats as they bake! If you give it a go please do let us know how you get on.

  • OMG, my cat, Tigger, goes beserk over these! And since catnip is part of the mint family, it still can be consumed by humans! (boyfriend ate one on a dare and liked it). Thanks for posting recipe.

    • Hi Debbie,

      This made my day! I’m so glad they’re a hit with Tigger – and your boyfriend 😉 – you’ve inspired me to whip up a batch with catnip this afternoon :).

      Best wishes,
