He’s only 6 weeks just now so still got a few weeks to wait. From the same rescue as our other 3. We are all arguing over names just now - my favourites are
Loki
Obi
All suggestions welcome 
Can’t believe DH has agreed to a fourth cat. Hope the other 3 are ok with him, I’m sure there will be hissing then they will be ok in a day or two, the big two were fab with the last kitten.
