so there are these two stray cats that just hang around my place all day, one male and one female who's pregnant. I've been giving them mixed rice and milk (only a bit) and boiled chicken twice or thrice a week.

now im thinking about getting them actual cat food. i read that dry food isn't good for cats since they dont drink enough water on their own. if so, what do i do to keep it moist?

i heard that brands like purepet and whiskas aren't healthy for them either, but they're the cheapest options i can find. chicken is pricey too. what's my best move here? I'd really appreciate any suggestions for cat food that's better for them. also, if anyone can help out with some cat food donations, that'd be awesome too.
