Odin was at the vet last night- the vet had a really good look at him and said she couldn't see any real problems, besides the fact that he has fleas and ticks. So all 3 cats are on Frontline for that now.
He also went from 6.2 kg to 4.3 kg so he lost nearly a third of his body weight! We are continuing lots of small meals and he is doing very well with that so I guess it is just a matter of time and patience to get him back to his fighting weight!
Odin has been so cuddly, he is always right there waiting for one of us to sit down and cuddle with him, I really think he is glad to be back, but not half as glad as we are!
