My Mum has two dogs both female one is a boxer cross and the other is a greyhound cross both are soppy things,
Recently they got two kittens to replace our cat Harry who died
as our cat ratbag was pinning , they were only going to get one but ended up taking the two male kittens 
As they are going to be kept in until they are done which will be in march, My mum was going to keep them away from the dogs but the kittens escaped their part of the house and into where the dogs were thankfully they get really well and the cats love jumping on the dogs
The dogs love the two kittens and are acting like mums to them is this a common thing ?
