Nancy and I have noticed that this litter is especially cuddly. They act like a bottle fed litter. We suspect this may be because they are getting less tactile stimulation. Bridget is not spending much time with the pups, partly because of the heat, but also her general attitude towards this litter - she is ready for retirement. With the warm temps, the pups tend to spread out and sleep individually. But now that they are seeing and walking more, they are starting to interact with each other.
