Miffy's weight

Hi

Miffy (A lionhead) has early stages of renal failure (he is nearly 8) and although he is in no way suffering (I am in regular contact with my vet and he is about to have another blood test etc) he has lost a fair bit of weight.

To make it a little more complicated the poor little thing has also now lost all of this teeth (a sweet relief for him in some ways as they caused him alot of discomfort and frequent vet visits)

I have mastered what to feed him and he is always greedy, but I want to bring him back up to the 190/ 200 kg mark (he is 170 at moment). Due to his age and his frailties I must admit I have now weakened my own strict rules on what I feed him and sometimes he get a lick of peanut butter! Any ideas what I can feed him to keep him energised and healthy for his condition?

Currently he has very very finely chopped dried grass, softened nuggetts with water and crushed into a powder that we call "sludge", green veg that I blitz in the food processor into tiny pieces, v. finely chopped tomato and cucumber (and 2 sultanas a day!) He is on excel mature nuggets which has glucosimine, cranberry and ginseng.

Ideally I would like to put something into his "sludge", say something with lots of fibre, but it has to be a powder or very finely chopped. Oh, and he also has arthritis!

I would wonder about adding in junior pellets because they have higher protein so add weight easier (mature pellets have a much lower protein due to being less active generally). I would also wonder about soaking oats in hot water and then adding those in (rolled oats, not quick, or instant or flavoured).

I'm not sure what you can add in terms of fibre though, maybe a high fibre count pellet? SS junior maybe?

yes the porridge thing is a good idea, he loves stuff like that, just plain oats with warm water. (if i let him he would eat the sweet stuff but I wont!)

The junior nuggets is a good idea too and had wondered about this too. Anyone else?

Sky-O's advice is excellent as always and I have no more suggestions. Didn't want to read and run though.
