A poisoned Russian double agent’s cat and two guinea pigs were taken from his home to be tested, according to a source.

Sergei Skripal’s pets were removed after the 66-year-old and his daughter Yulia, 33, were found unconscious in Salisbury after being attacked with a nerve agent on March 4.

They’re both still in a critical condition in hospital and it seems officers are also concerned about their pets.

‘Nobody has seen the poor pets since the poisoning,’ a source close to the family told the Sun.

‘I understand the cat and the guinea pigs were removed from the house and taken away to be assessed.’

Mr Skripal is very fond of his £1,500 black Persian cat called Nash van Drake and apparently spent thousands of pounds bringing the feline and gunea pigs to the UK from Russia.

His vet Howard Taylor said he offered to help after he found out Mr Skripal had been poisoned.

The 56-year-old added: ‘He was a nice chap and we got on well.

‘He never said he was in fear for his life. He used the vets for some years and I had seen his cat and his guinea pigs.’

Meanwhile, Russa has announced it’s expelling 23 British diplomats in response to the same number of its ambassadors being ordered to leave the UK.

The Kremlin warned it was prepared to implement further measures if Theresa May continued to punish it.

The Prime Minister has been seeking a global coalition of countries to go against Moscow.
