Do you know about how much will cost you if your cat is sick? Do you want to pay insurance or medical cost for your cat? Please think about it carefully. Pets need owner's commitments for their whole life. You can't just have them for temporary happiness.
FYI. One of my cats just got FLUTD(one of very common urinary disease for male cat, and can reoccur in most case) last weekend, and cost me about $600 for the first time treatment. The cheapest cat insurance is $10/month.
