wat do u think happened to crookshanks at book 7 wen the burrow was bein ambushed?

I think that when the charms were disabled and everyone was screaming, he ran into the wild.

from wiki:



During the height of the secondo Wizarding War, Hermione and Crookshanks came to stay at the Burrow, but Hermione left with Harry and Ron after Bill Weasley and Fleur Delacour's wedding reception was interrupted da Death Eaters. It is unknown what happened to Crookshanks while Hermione was searching for Horcruxes with Harry and Ron, o if they were ever reunited.


I'd like to think that Weasleys took care of him
