Being a versatile person and lifelong pet mom, I've experienced animals in all stages of life from bottle feeding kittens to teaching old dogs new tricks. It is possible. I currently have two senior cats, both since they were kittens. In 15 years they've had unique situations and varried interests that we as a family have adapted to such as traveling, fostering, and aging. Currently I am carrying for a senior dog that has weather anxiety and likes pillow forts in bad weather. Also with me is a 2 year old foster who loves the park and snuggles but is not good around some small dogs. I was able however to acclimate the large dogs to living peacefully with my two cats. It was a precarious situation at first. Both dogs love car rides as well as one of my cats. He might think he's a dog. I do my own pet bathing and grooming (trimming nails...polish, brushing, ECT.) I have also raised puppies and have worked with and house trained both cats and dogs. While walking the dogs we work on their social skills when encountering other people and animals.
