Now this is the first time we are gonna have a mix of the two. And to be honest I think my cats will do fine but the thing thats gone over my head is the whole flea and worming issue. Since my cats are strictly indoors Ive not wormed or flea them minus when they went to the vets for check ups and shots. And once when we first got Horris. So now adding a dog into the mix is gonna change things up I assume Were lucky that when we brought Decker, Horris and Soda none of them had fleas and none bar Horris had worms. How do you owners of both deal with this? I had tried a collar for fleas on Decker when I first got her for fear of fleas but it made her sick.
