Many years ago I was a breeder of Persian cats and at one time, one of my girls gave birth to two stillborn kittens.
She had always been such a wonderful mum, and I was fully aware that she would feel lost without her babies.
We are fortunate enough to have a large Cats Protection League centre just 10 minutes down the road, so the very following morning I popped in to see them, told them about what had happened the previous night, and asked whether they had any kittens that might benefit for having a surrogate mum.
My timing couldn't have been better. They had 3 kittens who'd lost their mum (the owner had let her outside when they were only a day old, and she's been run over), and the manager at the centre had been hand feeding the kitten's every hour, on the hour, 24 hours a day for the previous 3 days.
They were due a vet checkup that morning, but she said she would bring them to my home afterwards to see whether my cat would be interested in looking after them.
She arrived a couple of hours later. I say on the floor by my cat's basket and held out one of the kittens for her to sniff. She immediately scooped it out of my hands and pulled to straight to her belly. I took the second kitten and she scooped that one out of my hand to, as well as the third.
The CPL manager just sat and cried, she could barely believe how readily my girl had accepted these babies.
One of them did have a medical issue and hadn't been thriving whilst being hand fed and the vet had suggested euthanasia, but we said we'd like to try putting it with my girl. Unfortunately, we lost her after about a week, but the other two thrived and went back to the CPL at 7 weeks, and were returned to their original owner, who named one of them after my cat.
The same day they left us, I was asked whether I thought my girl would be prepared to take on another 3 orphans, but these were a week old.
We repeated the sit on the floor for a sniff as if don't previously, and my gorgeous girl just scored them to the warmth of her belly, and she looked after them for the next 6 weeks, before they went back to the CPL for rehousing.
I was so proud of my wonderful girl. She went on to have one more litter of 3 beautiful babies herself 18 months later.
It broke my heart when we lost her to an illness a few years later, and I felt I couldn't have more Persians after that, so I researched other breeds and changed to British Shorthairs instead.
One of my BSH girls was prone to very big liters (her first was 9!), so from her second litter onwards, I intentionally had another girl with kittens (usually 4 or 5) at the same time as her. They shared a massive bed in my nursery, and you'd see both mums forming a circle around a mixed pile of all the kittens (each time there were between 15 and 18!). They shared all caring, feeding, washing, etc, taking it in turns to have a little free time to eat, toilet, come to us for cuddles, whilst the other kept an eye on the sleeping pile of little ones.
It was so beautiful to see all my girls being so loving to ALL the babies they came into contact with.
