Hello there AP. First let me say that I am sorry about Moshu and I have been following your main thread and he is a beautiful boy. I don't know where you are in London but if you ever need a specialist exotics vet, the best one is CJHall so do check out their website.
Please take any advice from Vectis and Soufflé before me because of their huge experience. My Mocho has needed daily medicine for 8 months now. He has Cushings. Luckily it must not taste bad because he takes it mixed in baby food or porridge and now I can leave it for him to take from a little bowl himself. I took advice from his breeder and Vectis at a show.
Fish cat food I believe is fine but the best is kitten food. You can get a box of different flavoured pouches. In the end my Mocho will only accept the turkey flavour! Even then I only use the jelly surrounding the pieces which he likes. I expect it is strong enough in flavour. At least you have cats who can eat the rest of a pouch. I freeze it in tiny portions to rotate all the flavours of baby food. As Moshu is young he may well eat the pieces mashed up with the baytril mixed in. But, many hamsters won't take baytril this way. Their excellent sense of smell means they reject the food mix. If you can master scruffing him, then you are certain the medicine goes in the side of the mouth, it is over quickly and an indignant hamster can be consoled with a treat. Good luck.
