Firstly, apologies for the long post. - I'm after some help/advice on how I can build up and get some weight on my Seb. He's a 2 year old Moggy, he's not a big cat and has never been a big eater or food orientated. He's also a bit of a fussy so and so when it comes to food. I weighed him yesterday morning, the first time in a few months, he's gone from 4.4kg to 4kg. I think some of the weight loss is due to the hot spell we had as he was hardly eating. He wasn't well on Tuesday night, vomited a couple of times and wasn't himself, he looked and acted not well and his third eyelids were showing so we went to vets, vet said he could have a bug or be something he'd eaten, he was given an anti sickness jab, anti inflammatory and antibiotic jab, I was told to feed him bland food for a couple of days, if he was no better to take him back. He's a lot better now and back to his usual self. I was feeding him white fish which he loves. He won't touch chicken. The only food he will eat is Bozita pâté, Natures Menu pouches, Sheba trays and has the occasional dry Acana/Applaws and will not touch any raw. I'm willing to try anything with my skinny little man. Nicola suggested I try mice and doc, I'm sure I can get mice from my local pet shop, I will give them a call and ask, where would I get doc from? Any advice is really appreciated.
