Apparently being inside the same cage as a kitten is very scary for these two pugs. Destiny has it for them be put together although they belong to different species. And just maybe the poor puppies have never seen a kitten before and just do not know what to expect.
It is clear that they are very confused. At one moment they barf at her loudly, and just when she reacts and starts approaching them they go crazy scared. They were ready to ripe off the cage just to escape form that tiny sweet kitten.
