Before using custom furniture you will need to enable custom content in your game AND download and install the CEP from Mod The Sims.

The Sims games are technically made for real-life simulation. People have fun with different personalities and lifestyles and exploring them all. One of the worst realism mods is the bed-wetting mod that brings the uncomfortable childhood experience into the Sims world. And for anyone who knows Sims, it takes them way too long to clean up any.
I love the ACR mod, since it makes my sims do romatic interactions on their own which is really cute. I always missed that. You can also type in on google 'Sims 2 most used mods' since it will provide you links and other people who might know some great mods that we can't think of.

Adoption & Selling Pets
1.) Stray’s Always Accept Adoption– This mod prevents strays from refusing to be adopted.
2.) Pet Adoption Service Enabled For Kids– This mod allows kids to adopt pets from the pet adoption service.
3.) Give Pet Up For Adoption Enabled For Kids– This mod allows kids to give up pets for adoption via the adoption service.
4.) Pets Cost Less– This mod reduces the cost of pets from the adoption service by %50.
5.) No Sell Pet Want– This mod prevents sims from getting the sell a pet want.
6.) Sell Pets Easy– This mod makes the outcome of selling pets to other sims always accepted.
7.) More Pets Allowed In Family– Have up to 12 pets in your family household.
8.) No Pet Runaways-Pets never run away on their own.
9.) More Pets Allowed In Family– This mod allows you to have more pets; The default is changed from 6 to 9

Aging Mods
1.) Pet Years– Sometimes you don’t like the length of age span of Pets. This one shortens them.
2.) Dog and cat pet age duration– This hack decreases the lifespan of pets for their adult and elder life stages. Without a hack, pets can live up to 41 years which is very unrealistic compared to real life where most pets are lucky to reach even 15-20. The human ages in the game are more realistic, being 60-70 on average. So the hack is decreasing (by default) the pet ages for the sake of realism and to make the game more enjoyable (not having a house full of pets that seem to live forever).

Aspiration and Wants
1.) No Pet Obsession– Lowers the fun advertising of interactions between Sims toward Pets (not the other way around). Sims will now get wants related to pets only if they are in their family or if they are friends with the critter, and wants are also dependent on a sims interest in animals.
2.) No Pets Lifetime Wants– This mod makes the lifetime wants raise 20 puppies or kittens, have 20 simultaneous pet best friends, and have 6 pets reach the top career level impossible to roll. If a Sim already has one of those lifetime wants assigned, it won’t change until you fulfill it, change the aspiration or reroll the lifetime want using a hack.
3.) No Adopt A Pet Want– This mod prevents sims from getting the adopt a pet want.
4.) No Pet Wants Collection Alternate Version– This mod prevents sims from getting all of the pet wants listed below. Play with pet(only prevents adults & older)
Give love to pet(only prevents adults & older) Feed pet treat(only prevents adults & older) Rub belly(only prevents adults & older) Stroke pet Pet gets job Teach bird to talk All of the teach pet wants.

Bad Behavior
1.) No Autonomous Chewing or Scratching-This mod prevents pets from autonomously chewing & scratching sofa’s, chairs, beds, trash cans, & doll house’s.
2.) No Howling at TV’s & Stereo’s– This mod prevents pets from autonomously howling/barking at TV’s & stereos.
3.) Pets Leave The Flowers Alone– This mod prevents pets from autonomously eating & rolling in flowers.
4.) No Autonomous Howling At Karaoke Singer– This mod prevents pets from autonomously howling at sims when they are singing with the karaoke machine.
5.) No Pet Destruction– Pets will no longer destroy your furniture from scratching it.
6.) Simsky’s “No Pets Flower Beds” mods (pets will not destroy your flowers)– What it says.

Bathing & Hygiene Mods
1.) Dog Bathtub Only– Now no sharing a bathtub with the dog!
2.) Pets Beds Stay Clean– This mod prevents pets beds from getting dirty, this is a global mod so it should work with all dog houses, etc.
3.) Always Fresh Litter Box– This mod keeps the cat litter box clean.
4.) No Autonomous Munch Out– This mod prevents pets from autonomously eating from the litter box, it also enables you to make them eat from the litter box.
5.) Use bush enabled– This is a global mod that overrides the pie menu on shrubs, enabling the use-interaction for adult/elder dogs and cats. The interaction is autonomous, so you may see cats and dog seeking out a bush to pee on from now on. And of course, if you use boolprop controlpets on to control your pets, you will be able to direct them to use a bush by clicking on a shrub. The interaction is available regardless of bladder motive level, and regardless of if the pet is trained or not, so you should have it available all the time. Hooray for finally being able to tell our dogs when to pee, without having to train them first! We could already direct cats with the help of litter boxes, but could be useful if one for some reason does not want a litter box.
6.) No Autonomous Rolling In Or Licking Up Puddles– This mod prevents pets from autonomously rolling in & licking up puddles.
7.) Pets Leave The Trash Alone– This mod prevents pets from autonomously eating, digging, & rolling in trash.

Caged Pets
1.) Caged Pet Fixes– Fixed random bird death bug and other annoyances and bugs related to the birds and womrats. See readme for full details.
2.) Womrat Mod– This mod makes it so that sims have a small chance of contracting a mysterious disease when they get bit by a womrat. Servos and townies (except apartment roommates) are obviously immune to disease. Womrats are more likely to bite if their cage is not clean and when they are hungry.
3.) Close Bird Cage When Done– Fixes a bug that prevents a sim from closing the bird cage, When the sim is interacting with the bird and the interaction is canceled. With this mod installed Sims will always close the cage door, When the interaction is canceled.

Cat Mods
1.) Cats Hunt Roaches– This mod will allow your cats to hunt those pesky roaches that hang around causing disease and frustration among your sims. The action is autonomous and appeals to the cat’s fun motive. It raises fun and lowers hygiene (for playing with filthy roaches).
2.) Christmas Ornament Toys for Cats– The first toy is cloned from the catnip mouse, but shouldn’t overwrite it. Cats can play with it like with the mouse and it has a destroyed state like the mouse.
3.) Cat litter box cleanable by pregnant Sims– Allows cat litter boxes to be cleaned by all Sims, even if they are pregnant.
4.) Yowling Cat Fix– Fixes bug where scolding cats for yowling made them MORE likely to yowl.
5.) No Auto Finger Wiggle– Sims no longer will do the finger-wiggle game which inevitably ends in them getting hurt. Cats won’t ask for it either. Sadistic players can still direct a sim to do it.

Community Lot & Travel Mods
1.) Pet Hiking Motive Changes– This is a global mod that changes how hiking affects a pets motive, if brought along. It comes in two versions, only use one.
2.) Allow puppy kitten toddler riders– Permits a puppy or kitten to ride in a vehicle, to walk with you to a community lot, and to travel back home with you. Also has the same effects for toddlers.
3.) Allow strays on community lots– This hack re-enables stray pets to be allowed to visit all community lots, just like it was in the original unpatched Pets Expansion.
4.) Pet’s Don’t Visit Shops– This mod prevents pets from visiting all shops & community lots (While the shop is open).

Food Mods
1.) Pet food required– This is a global mod that overwrites the refill bowl code and makes it pull it’s food from a food box object rather than the box Sims pull out of thin air. The animation is unchanged, Sims will still appear to pull a box out of thin air and fill the box from it. But in reality they went and filled that box with food from the real food box, when you weren’t looking. Those sneaky Sims
