what i do is put money away in a savings account. If you have the will power to leave it there only for emergincies it is the best thing to do in my opinion. esp if you have more than one cat, i have 5, ranging from 6 months to 14 years. To insure them all would be a hideous price. Vet bills can be expensive, vienna one of my cats cut herself on her belly, about an inch long. it cost me nearly £100 to have her treated, luckily i had money in the savings. But yeah getting back to it, id go with savings. Most insurance companies that i searched about will treat for things like diabetes, but only up to a maximum emount of £££ per year.
