In the mid 90s, specifically 96 IIRC, I watched a tv show with my baby sitter. The show aired weekly and it had an old lady and a talking cat that I believe was an alien. It spoke telepathically. It may have even had a collar, like The Cat From Outer Space, but I’m not sure.
I believe the premise is the alien either crash landed or got to earth in an unplanned way and took over a cat or some such thing. The government was onto him. He ended up living with an old lady who eventually figures him out and ends up helping him shake off the government and work on geting home.
