Spot

Spot got shuffled from Enterprise crew member to member. She was best inclined to Reginald Barcley and Data.

In 2369,Spot scratched Riker forcing him to go to sickbay. The next year Laforge cared for Spot, since he wanted to see what having a cat was like, neither one found it enjoyable. Data unsuccessfully tried to train her, which Laforge teased it was Data who was getting trained. Worf tried unsuccessfully to give spot commands. Data made 221 different foods for Spot, he didn’t like many. Spot became pregnant. There were twelve male cats aboard.

In 2370 spot helped save the crew. A synthetic T-Cell became airborne and infected the crew causing them to de-evolve.  Data and Picard arrived back from an away mission to deal with the crises. Spot became an iguana, however her kittens which were just born were unaffected due to a defense in the placenta fluid, which protects infants from diseases that the mother may have.
