No idea how long for, but they have the boxes of 44 pouches - which are £10.99 at zooplus, or £10.50 if you buy them in 88s (ignoring any discount/cashback) at £8.99 for meat & fish, & £9.99 for just fish, which zooplus never have anyway.
They also do Doubly Delicious 12s at 3 for £9, & one of the other things at 2 for £5 - Kitten/Senior, maybe.
