Shipped via courier which is problematic for me but convenience of delivery to a local shop avoided all the hassle of rearranging missed deliveries!


Brilliant service. Super fast delivery


In our first tray the tins were slightly dented but in the second tray one of the cans was so dented that it had blown & the mouldy contents were open to view!
Very disappointed as this was our first time using your company.


Great service received the parcel the next day. Would defo go through this company again and highly recommend.


Excellent, prompt and consistently reliable service that we have used now for several years. I would have given a higher rating had my last two orders not have been short of content. However, the mistakes were rectified by return of post without question.


Easy to use website, good prices, fast delivery


Quick service and reasonable prices compared to ridiculous prices at the vets.


My on-line order was dealt with promptly and received by 1st Class mail 2 days later.


Their service is friendly, positive and helpful, always willing to answer any queries if they can.


Prompt service.
