Side-by-side comparison of two popular breeds — temperament, exercise, grooming, lifespan and common health issues. Use it to decide which breed fits your home.
The Ocicat (3.5–7 kg, 12–18 years) and the Siamese (2.5–5 kg, 12–15 years) sit in different — or sometimes overlapping — corners of dog ownership. Here's how they really compare for an everyday Irish or UK family.
Both breeds have similar energy demands — Siamese tips slightly higher but neither is a couch dog.

Highly active and play-driven. Need interactive toys, vertical space, food puzzles. Many do well with a feline companion to play with.
Short, fine coat. Weekly brushing is plenty.
Generally healthy. Watch for: amyloidosis, asthma, dental disease, glaucoma, eyes (some lines have crossed eyes which is harmless), separation anxiety.
