The RSPCA says a severe drop in donations means that centres including Putney Animal Hospital might have to close.
The centre treats over 7,500 animals each year, and is the only 24-hour animal hospital in London.
Putney MP Fleur Anderson is speaking to the RSPCA today, and presenting her separate petition to them.
