Besides the cat issue which I agree 150 % with advice given over and over.

I have no idea how you can stand to get bitten over and over by fleas and god knows what else?

I know you have limited ability to actually do something but anyone can do 15 minutes of cleaning a few times a day..... the time your taking to respond here you could have accumulated a bag of trash to be tossed out.

I wish you would help keep your cats healthy, it's the least you can do.

How is your personal hygiene? Do you shower daily, how do you treat all your bites? Keep them clean ?
