Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to shoulder train a pet rat [title] Let your rat get used to his new home. [step] When you first get a pet rat, give him at least a week to get used to his new surroundings (and to you). Your rat needs to feel comfortable and safe before he will respond to training; rushing into this will not produce the results you're hoping for.

Ending1: Give him a small toy or two when he first arrives (some experts suggest not giving a rat lots of toys too quickly). Over time, he should be at ease with the presence of something else. Ending2: [substeps] Try to provide plenty of room for your rat to move around his cage. Fill small spaces and avoid areas with too much food. Ending3: [title] Use feliway on your rat. [step] Feliway can be very relaxing and soothing, but is sometimes stressful. Ending4: [substeps] Sit near your rat's cage for 5 minutes at a time, several times a day and talk softly to him. This will help him get used to your presence and voice.
