Sure you could eat them if you really wanted to. And yeah cats are fun to catch. When i went down to Lake Havasu last summer i caught a few big ones, they give you a good fight. Cats will just eat about anything as long as it smells really bad, Night crawlers is a good bait for cats. Just put about 2 or 3 on your hook.Well i hope this helps, If you wanna catch cats go to the catfish post and read what people have posted there. Good Luck!!!
