The advantage of pre-set funds for your pets is that when you constantly follow the market, you notice that there are discounts and promotions that you can take advantage of, so that at the end of the month, your pet fund will have an amount of spending on things that are not necessarily essential. Also, an emergency fund is just as important as one for daily necessities. An emergency fund is the money you set aside each month in case your pet gets sick or needs a vet visit. Everybody knows that vet visits are quite expensive, but when you build an emergency fund you are prepared for such a situation. The money that remains at the end of the month from the pre-set fund for the needs can also go into this fund.
