I rescued a stray mom cat with one kitten. They have both been with me for about 2 months now but the mom cat won't take a rest on the begging for food. She has weened her kitten but wants to eat like every 2-4 hours. I had her treated for parasites and worms however she still looks a little bloated in the belly. I was thinking I should do this treatment again but really can't afford the vet this month. Can I get those treatments over the counter? Is the begging and the bloating related?
