You can use addObjectsFromArray: from NSMutableArray class

all = [[NSMutableArray alloc]init];
[all addObjectsFromArray:animal];
[all addObjectsFromArray:color];

and don't forget to initialize all ... – Martin R Apr 15 at 10:58
there is an error in the initialization, you miss a '[', and you can use initWithArray avoiding one instruction – tkanzakic Apr 15 at 11:01

Try this:

animal = [[NSArray alloc]initWithObjects:@"Lion",@"Tiger",@"Dog",@"Cat",@"Sheep",@"Wolf", nil];
color = [[NSArray alloc]initWithObjects:@"Blue",@"Red",@"Yellow",@"Green",@"Black", nil];

all = [[NSMutableArray alloc] init];
[all addObjectsFromArray:animal];
[all addObjectsFromArray:color];
