How quickly do you deliver?

Under almost all products on our website is an Estimated dispatch time, check this for a delivery prediction specific to the item you are looking to purchase. These badges are updated live based on the stock levels we have and also those of our suppliers - so are usually very accurate, but cannot be guaranteed. In more general terms, we aim to dispatch all orders within 1 working day of receiving payment (and a prescription if required). If we cannot do so within 3 working days we will contact you by email.

What do you charge for delivery?

For UK delivery, we charge the following:

Prices quoted are for delivery to all parts of mainland UK except certain Scottish postcodes (where the price is higher for items sent by courier. Delivery of food abroad (including Channel Islands, N. Ireland and other islands around the UK) is charged at a higher price and free delivery is not available. Temperature controlled products, such as Insulin, are also not always subject to the standard and/or free delivery options.

For full information on our delivery charges, including prices on heavy deliveries to Scotland and abroad, see our delivery information page.

We can deliver most items to all around the world, but prices do vary. The majority of light weight orders (less than 1.5kg) can be delivered for a flat rate of £10.

Delivery of aerosols

Due to restrictions aerosols can't be sent by Royal Mail. We appreciate your understanding.

Delivery of temperature controlled items

Some products, such as insulin and frozen food, need to be delivered in insulated packaging to prevent them from getting too warm (or too cold) during transit from us to you. Purchasing any of these items in your order will result in a £1.99 charge being added to the total to cover the high cost of the insulated packaging materials. You only pay the £1.99 once per order, regardless of how many temperature controlled items you purchase in that order.

Q & A

Below are some recent questions we've received regarding Hills Science Plan Healthy Ageing 11+ Cat Food, including answers from our team.

3 July 2014 at 5:10pm

Is the omega 3 and 6 content enough for dry skin?


Our vet doesn't sell Hills Science Plan 11+ for cats so have always bought the senior/7+ for our cat (male); a rescue cat guessed to be 12 yrs old by vet. She advised a supplement of omega 3 and 6 for his dry skin (not hugely dry; and fur is very silky) but I am wondering if there would be an improvement if I switch to the 11+ Science plan dry biscuits without the supplement.

Many thanks

  • Non-Executive Director

Unless your cat has an unusually high requirement for these oils, this Hills diet should contain adequate levels. I would suggest trying the diet just as it is. If you notice any change in the skin then it is possible to add supplements to it, but this is not usually necessary. Changing the rest of the diet can alter the overall balance of many things and supplements which were previously of benefit, might not now be needed.
