to Purrs.....
Your neighbours furbabe is lovely!
I would dare to say that he is blessed with being of the Heinz 57 breed....yes a moggie! Very handsome though!
An oldie may be a great option for you and your OH (other half), they do not need as much attention as a younger cat would require.....All cats have different natures/personalities etc....you could get two identical cats with two totally different characters....best to have a word with one of the people in the "Rescue & Re-homing" sect....there is lots of lovely cats needing homes!
Re: The allergy advice....lots of hoovering, dusting etc....groom your cat regularly to minimise floating fur.....wash your hands after stroking cat....and if all else fails get some anti-hystamine in!
Good Luck with your allergy test!
