zooplus.co.uk (I'm not on commission, honest ) Higher quality cat food (much better meat content than supermarket stuff) and bought in bulk. I use animonda Carny but there are many others to choose from.. delivery in in a couple of days. I find they eat well, don't just lick the jelly off and because it is higher in meat content they are satisfied for longer. I also use dry (Royal Canin) for free access eating.
I have three cats, (two Maine Coon youngsters and greedy!) and have found it much cheaper to order from them, than buy in the supermarkets.
Ours (2 x smallish indoor females) get a bit of a handwoven quinoa style diet but they seem quite happy with it and don't always finish their meals, and it makes me happy to feel that they're getting decent grub:
20g applaws dry each a day, so a 2kg pack (£11.99 on Zooplus) works out £1.67 a week.
1/2 each 200g tin of grau grain free (£24.90 for 24, zooplus) so £7.28 a week. We should really buy big tins which would be cheaper though.
Let's add 25p as dreamies tax.
£9.20 a week. Cheap at the price, they're better than telly.
i have four cats so double the cost and mine cost me 7 tins of food a week butchers classic so around £3 and a bag of harringtons chicken and rice biscuits a week so £5 so two cats four pounds a week to feed
Buy it from zooplus (google it) it's a really good bulk-buy website for cat and dog supplies.
This month from that site I got 40kg of cat litter for £20 which is flushable, and I got 4kg of high-quality James Wellbeloved housecat also for £20. The litter lasts 2 cats about 3-4 months and the food about the same. I free feed and then they share a pouch in the morning and again in the evening.
I found that they are more of the cheaper supermarket brands before they got full as they tend to contain a lot of "filler" without substance.
