In general the default for cats and dogs is the male form, though it can be ambiguous between male and don’t know / don’t care.
For instance if you saw a random unidentified cat you could say you saw “un gat / gato / chat”, and it would be impossible to tell whether you were referring to a male cat or a cat of unknown gender (while if you used the female form it’d be unambiguous).
Romance languages really could use a neutral form, but “gat@”, “gat*”, or “gatx” just don’t work when you try to figure out how to say them out loud, and using the female form for neutral just moves the problem to the other side.
