How wonderful! She looks beautiful! Does she have a name?
I think a cat is a good choice for someone with fatigue. When you're really tired they can take care of themselves and they don't necessarily need daily walks like dogs do. And cats often enjoy curling up and snuggling while you lie down (although this little lady might be a little active for that!).
I look forward to hearing about your adventures together!
Suggestion for a pet. Get a Dogman as a pet. They are very intelligent and can be bipedal. Height can go from 7-13 feet. Very fast and quick. They easily can go at least 80+ mph. Powerful swimmers. Geographically they are seen all over the world ... all over the continental US ... north, central and south america, new zealand, australia, UK, Europe, Asia, Africa. Hallmark feature is it's hind legs being like a dogs with german shephard face. Doesn't he look sweet.
If anyone has a Dogman they don't want, just let me know. Dogman would be such a good companion to have.
