One idea could be getting your dad a personalized cat mug with a picture of his favorite cat. Another idea could be getting him a cat-themed book, such as "A Street Cat Named Bob" or a cat-themed cookbook with recipes for cat treats. You could also consider adopting a cat in your dad's name from a local animal shelter or making a donation to a cat rescue. If your dad enjoys puzzles, you could also get him a cat puzzle, or a cat-themed board game to play with the family.
Or you can get him a star map with the date when he welcomed you in this world.
