What Makes a Cat “Large”?
Size is quantified typically by weight, length, height, tail length, and muscle density. Most domestic cats weigh around the median of 8 to 12 pounds meanwhile the larger breeds commonly weigh 15 to 25 pounds and above. Furthermore, certain breeds like the Savannah or African Serval crossbreeds tend to break the norm even further because of an added genetic mutation or because of their wild ancestors.
In addition to increased weight, larger breeds also have:
- Increased size of their paws and length of their tails
- Increased likelihood of an athletic build for predation
- Extended patterns for their growth and developmental cycles (3 to 5 years)
- Increased dietary needs for nutritional intake
These larger breeds require fulfill of their enrichment and spatial needs through the addition of branches and levels to climb. Additionally, structures like cat trees, cat wall shelves, toys and various games are also beneficial.
