ProZinc Insulin For Cats 40iu/ml 10ml Vial

ProZinc Insulin is a protamine zinc insulin created specifically with cats in mind.

ProZinc works quickly and effectively to regulate blood glucose levels.

It is available in single vials of 10ml.

Protamine zinc insulin formulations are typically effective for 10-14 hours in cats.

Prozinc needs to be kept below 8°C to ensure its efficacy. During periods of hot weather dispatches may be temporarily delayed. Do not freeze.

All our Prozinc is shipped with cool packs and in insulated packaging. Further to this we do NOT ship Prozinc during prolonged periods of hot weather. However, even  with these temperature control safeguards in place it is impossible to guarantee that the product will stay at the manufacturer’s recommended temperature of 8°C or below during the dispatch process - as we have no control how it is stored after being collected from us and before it gets to you.

In addition the manufacturer recommends that all Prozinc is stored vertically. Again this is functionally impossible to guarantee or police during transit.

We are unable to deliver to Northern Ireland.

This is a prescription item and will be sent once a valid prescription is received.

This item will only be dispatched Monday-Thursday.

Separate ProZinc syringes  are available for sale separately. We would recommend that only these are used as the dosages are specifically designed for ProZinc.


If you see the "prescription required" sign next to an item you’d like to order, it means the item can only be issued with a prescription. While you can add these items to your shopping cart and pay for them along with other non-prescription products, we can’t dispatch them until we’ve received a prescription.

    "The website was easy to navigate and had a large range of different items available, including veterinary/healthcare, food and accessories, for domestic pets plus horses. They offer a wide variety of delivery options with clear information on expected arrival dates and how much it will cost. Payment for orders was straightforward and could be made by credit/debit card or PayPal. When placing an order for certain non-prescription veterinary or healthcare items customers were required to provide information about the animal they were purchasing it for to ensure that it would be suitable for them. I thought that extra layer of safeguarding was a very good idea."
