The Momma Cat I would name Tubbette after Tubby and Tubby 2 Angels so shewould have Two Guardian Angels.
No 1 Kitten Rascal as there mischier in those eyes.
No2 Kitten Geoege because he looks like our family Cat Geoerge at that age.
No 3 Kitten Pirate because this Kitte will still your heart. No 4 Kitten Sinbad beacuse thats an exploring Kitten if I have ever seen one.
We hope you like my ideas as those are the first names that came to mind.
