It wasn't until a day after he arrived at his destination that Grimmer heard faint meowing - and enlisted some of his coworkers to help dismantle the car and investigate.
"He must have had a long journey but remarkably is unharmed," Grimmer said on the Royal Navy's website. "I am never late for work and was left with no option but to take my new friend in with me."
Grimmer's squadron immediately fell in love with the little kitten, and named him Tigger, because he has tiger-like stripes. Oh, and the helicopters the squad flies are referred to as Flying Tigers.
