Unfortunately I do not have enough context to definitively state how many babies Lisa's cat had. The key sentence is: "Ihre Tatze hat 3 Junge bekommen - die kleinen sehen sooo süß aus." This translates to: "Her paw had 3 young - the little ones look sooo cute." The use of "Tatze" (paw) seems unusual when referring to a cat having babies. It makes me unsure if this is referring to an actual cat that had 3 kittens, or if it's meant more figuratively. To be safe, I would simply congratulate the friend on the new babies and ask her directly how many there are before stating a number. Apologies that I cannot provide a more definitive answer without more context to clarify the situation. Please let me know if you have any other questions!
