I came here for the comments
Why can't you translate this as 'Your cat is fatter than my cat'? Gros can mean big, large and fat.
I wrote "heavier" rather than "fatter" August 26. I think it, too, ought to be accepted.
I translated to larger..... you cat is larger than my cat....and it was denied
Le chat de ta mere est plus gros que mon chat...
"Heavier" should also be accepted here... after all, some cats just look big ;-P.
C'est ce qu'elle a dit.
