PROBLEM: [header] How to get your ferret spayed or neutered [title] Verify that your ferret isn't already spayed or neutered. [step] Ferrets sold at pet stores are almost always already spayed or neutered. Many breeders also spay or neuter kits, or young ferrets, before selling them. <sep> (A) This will ensure that your ferret will not be harassed or misredirected. [substeps] Ferrets that already have an owner must also be spayed or neutered before they sell them. (B) [substeps] You can get your ferret spayed or neutered immediately upon the transmission of your ferret, leaving a good deposit for a new starter puppy, but will have to go through much more patience. [title] Ensure that your ferret can still eat. (C) [title] Familiarize yourself with the type of breeding location you need. [step] The first hurdle in breeding a ferret is to get it spayed or neutered. (D) [substeps] Purchasing a ferret that's already spayed or neutered is in your best interest, since the operation can cost a lot of money. If the store is uncertain, you can also take the ferret to the vet.

PROBLEM: [header] How to care for hair between salon trips [title] Buy a deep conditioner. [step] You probably already have shampoo and conditioner. The conditioner you use regularly does condition your hair as thoroughly as a deep conditioner. <sep> (A) A deep conditioner will make your hair appear softer, shiner, and healthier. It should only be used once a week. (B) However, you're willing to risk starting your hair oily or looking like a buck without a deep conditioner. Look for a deep conditioner made specifically for you hair at your local salon. (C) But you don't want to purchase a deep conditioner as any hair at all. Invest in a deep conditioner and make sure you use it daily. (D) Choose a deep conditioner, spritz it on your hair, then shampoo, then blow dry. You can simply apply the deep conditioner once a day and then continue rinsing to replace it over time.

PROBLEM: [header] How to create an ecosystem in a bottle [title] Cut off the top of the bottle. [step] To make a bottle ecosystem, you will need an empty 2 quart (2 liter) plastic bottle. It is best to use a clear plastic so that you can see inside the bottle and make observations. <sep> (A) Cut off the top of the bottle, just below the neck. [substeps] To ensure your cut is straight, you can put a piece of masking tape around the bottle and then cut along the edge of the tape. (B) [substeps] Use a pair of small scissors to trim any excess plastic from the bottom. If you want to create an ecosystem, this will appear the most natural. (C) Alternatively, you can use the top of a soda bottle. [substeps] Using a long knife, cut a slit into the bottom of the bottle. (D) [substeps] Cut the top part off the bottle or just cut off any larger, rounded bits. The size of the bottle is totally up to you.
