My new kitten is now about 10 weeks old. I've realized he's gotten fleas and am now panicking, not exactly knowing what to do becuz he's my first. He was sleeping on a white pillow earlier and I realized that there were those "coffee grain" flea droppings on it when he left from his spot. I was planning to buy some medication from Petco, but didn't know exactly which ones I could use for a young kitten, so I was wondering, which ones would you recommend? Thanks in advance. What ones could I find in a pet store that could almost be just effective as vet medications?
