I have two lilac point Siamese kittens (4 months) brother and sister. People tell me that I should have them both 'done' at 6 months to prevent unwanted kittens, although they are house cats and never allowed out.
They are beautiful animals and I am undecided on what to do. I am worried about unrest and spraying if I decide to leave them both in tact. Would they mate if left fertile? This would surely be unhealthy.
I would be grateful for your advice.
