PROBLEM: [header] How to handle a kitten [title] Be gentle and patient when picking up the kitten. [step] Kittens are very small and fragile, so make sure you're using a very light touch and gentle care. If the kitten shows signs that it doesn't want to be touched, like avoiding your touch or running from your hand, leave it alone and try again at a later time. <sep> (A) [title] Handle your kitten slowly and with caution. [step] Depending on when you picked the kitten up, you may need to start with a short cuddle, and gradually move from there. (B) [substeps] Watch out for the mother cat, who may not want anyone handling her kittens. She may bite or scratch people to prevent them from touching the kittens. (C) Talk to a familiar person or pet when picking up the kitten if you think you can cut away some of its protective protective bubble. [title] Avoid picking up the kitten from its mother. (D) Just imagine that you were picking your kitten up by its neck, holding one hand over its head, and guiding its ears, not gently placing one hand on its head. That gives the kitten shock, so be careful of hurting the kitten.

PROBLEM: [header] How to determine if you need a personal trainer [title] Hire a trainer to meet specific fitness goals. [step] One of the best reasons to hire a personal trainer is if you need help meeting a very specific fitness goal. They'll be able to guide and train you so you'll be successful. <sep> (A) There are several benefits to hiring a trainer : [substeps] Personal trainers are not only on-site but in-person.

(C) If you only need help with working on your problem areas, you'll have more support when your trainer comes in.
