I don't think it's possible to get Feline's Pride in the UK. http://www.finerbynature.co.uk were attempting to bring it in under their own label, but it looks like that's fallen through. Last time I spoke to them about it they were having issues getting it cleared by DEFRA. I guess they couldn't get it through testing.
The only freeze dried raw I've found in the UK is Nature's Menu Country Hunter cat treats. They're labeled as treats, but the company have told me that the recipie is identical to their raw complete cat food, but has just been freeze dried instead of frozen. If you rehydrate it, it becomes a complete meal. Just follow the feeding guide they have for their raw cat food
