Oreo and Pantera
My wife's (Portuguese) neice got a kitten that they named Pantera. Unfortunately, it transpired that her boyfriend is very allergic to cats, so they needed to give it away.
Since we'd just sold our old house, and were in the process of buying a new one, we had a bit of spare cash available so we agreed to take Pantera on (if it had been left in Portugal, it would've almost certainly be put down).
At the same time, Pantera's brother hadn't found a home - so we volunteered to take him as well. We called him Oreo because he's black and white.
We had to wait a couple of months to get the vaccinations done, and for them to have their flight from Portugal to the UK.
Raj took to them very well.
I would actually say that Raj acted as a 'big brother' to them. When they were first allowed outside of the catio I'd built, he kept around them, and made sure they didn't get into trouble.
One day, we'd lost Pantera and were calling him. Raj came up to us, and then led us to him (he'd gone a little bit further down the road than we'd seen him do before).
Oreo was badly injured when he was about 8 months old - it appears as though another animal had a go at him, and he broke his palate.
Due to his small size (I think he's got feline dwarfism), he had to go to a specialist vet who put a screw to fix it - and later on removed it because it was making him sneeze a lot.
But he's now recovered, and enjoying life. He tends to spend most his time indoors, unlike his brother who practically lives in next door's house. Raj is somewhere in between the two...
Pantera seems to be a bit of a bully now - although Oreo will occasionally chase him for a bit of a play.
