Hi there, this is Dr Linda, a UK based vet.
I'm sorry to hear this and understand your concern for Arcat,
The vast majority of cats are 'lone rangers' and dislike sharing their territory.
This is especially true of those who are not used to sharing their home.
It is not surprising he is choosing to spend time away, as he is actively avoiding any conflict. He is doing what most cats would do in his position and there is nothing 'wrong', though I understand you may want him to be home more.
It is also the case that the weather has improved so he is likely taking advantage of the warmer weather.
The smells from the vet and the fact that the cats would have been smelling and acting differently on return from the clinic may have unnerved Arcat.
Things that may help include:
Feliway 'Friends' is a newer one that is specifically aimed at multi cat households. It is by no means a 'miracle cure' but it helps a little, alongside the other things discussed.
I'd continue with the calming supplements, which should be helping to take the edge off and will work towards minimising conflict.
It's sensible to have the option of a litter tray if you can; especially with so many cats, in case there is something preventing them from going outside (such as fireworks or a bully cat). If we don't, episodes of cystitis and constipation can occur more commonly.
If it is needed, I'd continue with the separation, with the aiming of slowly re-introducing if tolerated. The aim is for content co-existence rather than friends (which is much harder to achieve and is not always possible depending on the personality types in the mix).
I do hope this has been useful and please let me know if there is anything else,
Take care,
Linda.
