Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to help your cat love his crate [title] Start as young as possible. [step] If you have the option, start crate training your cat very early. A small kitten will adapt easier to a crate than an adult cat that has a lifetime of crate distrust built up.

Ending1: [substeps] However, starting crate training early in life is not always possible and that shouldn't dissuade you from trying. Just because you have an adult cat, for instance, that doesn't mean it can't grow to love its crate. Ending2: Start by beginning the transition gradually by introducing new items quickly. [substeps] Not all crates are suitable for a young cat. Ending3: Begin crate training by placing him, along with all of the toys and treats, in the crate so he is not scared the whole time. [substeps] Toys should be placed slowly and deliberately, quickly, so that the cat cannot become overwhelmed, looking around and trying to pick up any toys. Ending4: To avoid the hassle of sudden changes in your approach to crate training, start a crate training routine when your cat is a kitten or puppy. [substeps] Either start your routine as early as your cat grows in age, or as early as your cat gets older.
